I’ve heard people talking about a "hot pot", which is supposed to be similar to an electric kettle, but you can cook noodles and rice in it. It is neither a crock-pot/slow cooker or a rice cooker. Does anyone know the real name for this appliance or where I could find one?
If a typical household electric kettle reaches boiling point at 100° celsius and clicks off once it has boiled, at what rate does the temperature decrease?
Lets say for arguments sake, how long does it take to descend to 96° celsius?
Is there an equation to calculate this?
Thanks,

Thanks Scott,
Could you calculate for a hypothetical example. Say a volume of 1 litre of water.

A typical modern plastic kettle in a room temp of approx 15° celsius… Just looking for a viable estimate.
Thanks

Ok Indra,
Please see above for edits relating to these variables you mention. I don’t know how to confirm the vessels thermal conductivity… Can we assume it to be some hypothetical value in order to calculate an example based on the aforementioned values.
Thanks again,
P
Thanks everyone. Good answers all round. Disappointed I couldn’t get something more conclusive without performing tests. Will have to use some type of a heat resilient thermometer. Will post results if I ever get around to doing it!
Gonna leave it up for another day just in case Hawking or peers stumble across this conundrum with a solution.
Can anybody actually construct an equation to calculate an approximation?

I lent my electric kettle to a guy on my floor in university residence. Without my knowledge (being the idiot he is) my floormate boiled milk in the kettle to make hot chocolate. I didn’t realize he did this until about a week later when I wanted to use it and noticed a foul smell coming from it. I rinsed it with some water and there were numerous flakes of dried milk in it. Also, the elements in the kettle appear to be coroded. What can I do to repair the kettle so i can use it again? Or will I just have to buy a new one?
How versatile are you in changing and repairing your home equipment?
Do you know how to service your own electric kettle, or your home TV, or change the water pipes of your house? Or perhaps even service your own car or motorbike?
Or are you helpless and need to call the repairman?
My friends tell me my electric kettle needs de-scaling!
But were at a loss as to what to do!
So what do I do / use to de-scale it with!
Can U buy powder or whatever and where do U get it from –
what sort of shop?
And what do U do – once U’ve got it!
(sigh im getting quite sick of this project)
what sort of physics concepts that have to do with electricity are at work in an electric kettle?
please give the specific principle/ concept. thanks.
Being a Brit i drink a lot of hot tea, the water is boiled in an electric kettle, so obviously it is boiling temperature. My question is i have been drinking hot tea all my life, is there any chance that the hot water can damage your esophagus or stomach?
I’ll need
Counter
storage
mini fridge with separate freezer door
hot plate
microwave
electric kettle
The communal kitchen is gross so I will probably only use it when I need an oven.
The dorm building is a converted hotel that was built in th early 60s.
No gas but I can do dishes in my sink. The sink and vanity are in a nook in the main room while shower and toilet are seperated so it isn’t really in the bathroom.
I have a couple of old small appliances from the 1920’s-1930’s (Toaster, hair dryer,space heater, electric kettle stove) in my house, and in all the time I have never had one break down once, and these things are beautifully made in art deco style and have lasted 70-80 years. On the flip side, I have had expensive hair dryers, toasters etc that have given out after a year or two. What do you think is better quality, does anyone else use vintage applicances?
In a doestic istallation where house hold items like electric kettle, iron toaster, fridge. TV, HiFi, Computer e.t.c. !3 Amp sockets burn out on the contact holes where the plug connects.
