i think 1kg of ice
1 kg of water at 0 degrees Celsius contains more heat than 1 kg of ice at 0 degrees Celsius. This is because the water has higher thermal energy due to its liquid state compared to the ice in its solid state.
The specific heat of water is 4186 joules per kilogram degree Celsius.
It boils
The specific heat of water is 1 calorie per gram per degree Celsius 1 cal/g/degree celsius
The amount of heat needed to raise the temperature of 1 kilogram of water by 1 degree Celsius is 4186 Joules, which is the specific heat capacity of water.
One calorie of heat energy raises one gram of water one degree Celsius.
One calorie is needed to heat 1 gram of water 1 degree Celsius
Yes, one calorie is the amount of heat needed to raise the temperature of 1 kilogram of water 1 degree Celsius.
cold
Gasoline has a less boiling point (72 degree Celsius) While water has a bigger boiling point (100 degree Celsius)
Latent heat of the ice, liquid water has no latent heat reserves. Perhaps at freezing we should call it "latent cold" but thermodynamics has always referred to it as latent heat whether at boiling or freezing. +++ It is latent heat because the water (liquid or ice) at freezing-point (0ºC) still contains heat energy as its temperature is at about 217ºK.
It takes about 4.18 Joules of energy to heat 1 gram of water by 1 degree Celsius. Therefore, to heat 1 liter (1000 grams) of water by 1 degree Celsius, it would require about 4180 Joules. Converting this to watts depends on the time taken to heat the water.
