It all depends on how much water there is. The more
water there is, the more kilocalories it takes.
Yes they generally have a heat element, similar to what's in a kettle. Many washing machines take in cold water only illustrating this ability.
That depends on what the starting temperature of the water is,and what temperature you want it to reach.If you expect to get a number, you must first give the necessary numbers.
Heat required = mass x specific heat of water x temperature difference Here we have heat required = 21 x 1 x 10 = 210 cals
Latent heat has the ability to do something in a given time period. Take a water heated radiator, latent heat has the ability to make the radiator warm or hot according to the temprature of the water. It will continue to do this until the water stops flowing through the radiator and the radiator begins to cool.
insulators although they take a long time to heat up, it takes a longer time to cool down. that's why if you heat water in a metallic container it takes more time for the water to cool down than the coontainer.
First we take 88 degrees and we subtract 15 degrees. We get 73 degrees difference. Then we multiply our 175 g of water by the temperature increase of 73 degrees. We get 12,775 calories. To get Kilocalories we must divide our calories by 1000. Why don't you do that?
It takes 1000 calories to heat 1 litre of water 1 degree C.
That's going to depend on the temperature of the water before you heat it, and on how hot you want it to be when you're done.
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
yes. the more water the longer it would take for the heating element to heat the water. the less water, the less time it would take to heat.
Yes they generally have a heat element, similar to what's in a kettle. Many washing machines take in cold water only illustrating this ability.
It does
ICE
You take heat out of the water.
It depends entirely on what the initial temperature and volume of the water is and how much heat is applied.
The specific heat of water determines how much energy is needed to heat water.
Swedish people take in 3120 kilocalories per day according to a 2005--2007 analysis.
