Kettle

Complicated question, considering it’s so simple. You can look up gas and/or electric rates in your area, in case the stove is gas. My take is that microwaving in a glass measuring cup heats up mostly the water and to some degree, the cup. Boiling water on a stove heats up the water, the pan, and half the kitchen. On that basis I’d pick the microwave.

Hi, I was trying to boil water last night on my electric stove. I remember commenting that it was taking longer than usual to boil – it was steaming like crazy but not boiling. Suddenly the water just exploded – and whatever water was left in the pot then began boiling happily away.

I’m assuming that somehow the water was superheated (which I know can happen in microwaves). But on a stovetop? What happened? How can I prevent this in the future?

For reference: I was using a stainless steel 2-quart pot, tap water, and an electric coil stovetop. Immediately before cooking, I had washed the pot with dish soap and a scrubby brush, rinsed well, and then filled with hot tap water.

That is a rare thing for sure. Too bad you didn’t get it on video! Most sites talk about it being impossible to happen on the stove.

I would suggest stirring the water occasionally and check for bubbles forming at the bottom of the pot. No bubbles = extreme caution.

More bio questions!!! yay! lol

2. Explain the following statement: the temperature of the water in a teakettle is higher than the temperatue of water in a swimming pool, but the swimming pool contains more heat.

3. How does acid precipitation form? How does it injure animals? Plants?

4. Explain why water molecules are polar, how this makes them tend to bond to each other, and how this causes water to have a large heat-storage capacity

thanks a million!

There is no need for me to repaet answers. The answer above mine is correct. 1, 2, 3 are correct.
Addition: 2.) You need to loo at the specific heat of water. Which raising the the water by 1deg C / gram. So, the pool has a lot more water than a tea kettle => more heat.
Addition: 3.) Since the precipitiation is acidic, plants: soil is acidic and animals: both the acid will damage vital structures and cells that the organism needs.
4.) Electronegativity. You need to know that oxygen is more electroneatve than hydrogen, so the oxygen will be slightly negative and the hydrogens will be slightly positive. This is a polar molecule because of this affect. Due to these charges, other water molecules are attracted to these charges, hydrogen bonding (+ with -). High specific heat because a single water molecule needs to break free from other water molecules surrounding it, which are attracted to it and won’t let go easily.
good luck.

It has a removable whistle, which came apart. I reassembled it and now it no longer whistles. Its interior has only a metal plate and a screw – did I loose a part?

Remove Whistle from Kettle
Fill the kettle with clean water
Replace Whistle
Place Kettle on Hob
Turn on heat to full
Stand back an wait
Once whistle screams turn off heat
Remove whistle
Pour BOILING water into appropriate container
Enjoy

*These are the most important ones!

THANKS:)

The easiest way is to look at the sides/back of such items where there normally is a rating plate. E.g. a jug kettle may be 3kw
Small items such as a calculator may be solar powered and use minute amounts of power.
Ipod – depends on the model and mode, will use more/shorter battery life for video than audio.

i saw this question in my earth science and thats all it said.

The answer will depend on the volumes of hot and warm water and the mass of the ice to be melted.

Certainly, the heat will transfer from hot water to ice more quickly than from just warm water. However, once the hot water cools to the same temperature as the warm water, the rate of heat transfer is the same. After that, if the smaller vessel becomes colder than the tub, the heat transfer will be slower.

Thus, the question needs to be more specific about the mass of the ice, the volumes of the pot and tub, and the temperatures of the water in the two vessels.

…w/o damaging the stove?
I would like a whistling tea kettle. Do you use one? What do you recommend? We have a burner on the stove that is a warming burner so I could put the kettle on that after the water is hot and it will stay hot.

We have one now and it really makes a lot of noise and seems to be ‘bouncing’ on the stove when it heats up. I am afraid it is going to damage the stove. I am thinking it is a mainstay brand but not positive as I don’t see the name on it. The pictures I have seen of that brand look like what we have though.

I see a lot of electric pots but I really don’t need another appliance for limited counter tops!

Would also like a ‘decent’ coffeemaker that makes GOOD coffee but isn’t really expensive! Is that a possibility now days? I have read so many different reviews on all types and get more frustrated each time! I have quit using the one I had and gone to making either ‘instant’ or one cup at a time with a filter that fits on top of the mug. What do you recommend for this?

If you’re having trouble with your current teakettle bouncing around on the warming burner, then it’s likely that you’ll have trouble with a different metal teakettle bouncing around. If it were me, I’d try one of those little Corning Ware teapots made for stovetop use. It might not have the tendency to bounce around when on the warming burner.

Warming burner: Sounds like a great option that I wouldn’t mind having.

Electric tea kettle: I am crazy about my Melitta electric teakettles. I have two. I use one upstairs in the winter when I want to snuggle in bed with continuous cups of hot tea of various kinds. I keep one downstairs in the kitchen for the same use.

Good coffeemaker: GOOD coffee depends both on the coffeemaker AND mostly the kind of coffee you use. If your coffee isn’t good, try putting a little more coffee in the basket to the same amount of water before you just chunk your coffeemaker. I have a Capresso which grinds the beans and then swings the basket over for brewing. It can be set up the night before. Very convenient and also a SPACE HOG. However, I find that it brews and drips a bit too quickly for the strength of coffee I’d like to drink so to fix that, I remove the pot during the first part of brewing so that the coffee in the brew basket has an opportunity to become completely soaked with water. Then I put the pot in. This extra effort only takes 1 or 2 minutes longer and it’s well worth it.

Try the above two tricks before chunking your coffeemaker for a new one. I can’t stand instant or the kind that brews in your mug like a teabag. YUCK!

we get up in the morning head straight for the kettle (we paid vat on the kettle) switch it on (vat on electricity or gas) put the tea in the teapot (vat on teapot) get in the shower (vat on electric) put on our clothes (vat on clothes) get in the car (road tax or vehilce license) start the engine (vat on petrol and oil and servicing) go to work, collect our wages (income tax and National Insurance) walk to the bank in our boots (we paid vat on) pay wages into the bank (and pay income tax on our savings) pop to the pub (vat on a pint) while we wait for our chinese (vat on the takeaway) go home watch telly (having paid vat on the telly, paying vat on electric to run it and the t.v. license) we get into bed and read a book (subject to vat) using the lamp beside the bed (which we paid vat on and paying vat on electric to run it) lights out and sleep but even as we sleep we are paying tax as the hours tick by on the clock (we paid vat on and vat on electric to run it – vat on batteries)
we grow old having saved towards our pension (we continue to pay tax on these savings and pay income tax on our pensions) – Have I missed anything?
Actually I did miss something – how could I have missed the most dreaded tax of all – We get up in the morning to collect the post only to find the council tax needs paying for collecting our rubbish the day before!

Its true we do pay a lot of tax but if you want to live in any other civilised, developed country then you will have to pay tax….. I bet you will be the first to complain if you gas and electricity stopped working a couple of times a day like it does in Greece, or the roads need relaying like most of Europe, or the police were corrupt like most of the world….. i could go on but i feel it would fall on deaf ears.

I’ve never had a problem with this using a gas stove, but now I’ve moved to an apartment, and it has an electric stove. Any advice about this is appreciated. Thanks.

You have to make sure your electric parts that you set your pan on is clean, nothing can be on them. and make sure the bottom of your pans are grease free and completely dry. I had that problem when I went from gas to electric, always clean them after every use.

umm my cousin is about 5-6 years old and she was playing around with the electric boiling pot. she got burned on both hands. As soon as her parents saw it they put ice on it. Then they brought her to the doctor said it is a second degree burn and they gave them some cream for it. WIthin a few hours blisters started to appear. Then they put aloe, and the cream that the doctor gave then on her hand. After a few days her sister popped her blister by accident. I want to know whould it leave a scar. And another thing her skin is wrinkly, I want to know would it stay like that, if it would stay like that what can they do to make it not wrinkly.

Be sure to keep the area clean, dry and apply anitbiotic oinment daily. Since she’s young if she has scaring it may be temporary as her skin is still growing and in a very supple state which helps to reduce the scaring. By the time she’s older any marks from this burn are likely to fade. Her parents need to be sure to take care not to allow the area to become infected.
