To calculate the kilojoules released when raising the temperature of water from 2°C to 80°C, you can use the formula ( Q = mc\Delta T ), where ( Q ) is the heat energy in joules, ( m ) is the mass of water in kilograms, ( c ) is the specific heat capacity of water (approximately 4,186 J/kg°C), and ( \Delta T ) is the change in temperature. For 1 kg of water, the temperature change (( \Delta T )) is 78°C (80°C - 2°C). Thus, ( Q = 1 \times 4,186 \times 78 ), which equals approximately 326,508 J, or about 326.5 kJ.
It would depend on the temperature of the water, or average kinetic energy. (KE) However, what you may be looking for is how much heat is needed to raise the KE, or temperature, of water. 4.184 kilojoules per gram is the heat required to raise the temperature of water 1 degree Celsius.
None. Now if you mean potential kilojoules if fusion happens, or the kilojoules at a certain temperature, that is something else entirely.
q(Joules) = mass * specific heat * change in temperature q = 32.0 grams H2O * 4.180 J/gC *(54.0 C - 12.0 C) = 5617.92 Joules this is, of course 5.62 kilojoules
That's going to depend on what temperature the water starts from.
It is harder to raise the temperature of water than it is to raise the temperature of a rock. It takes 1 calorie of energy to raise the temperature of 1 gram of water by 1 degree C, whereas it only takes 0.02 calorie to heat a gram of rock to that temperature.
To find the rise in temperature of water in a calorimeter, you would measure the initial temperature of the water, then add a known quantity of heat to the system (e.g. by burning a fuel), and measure the final temperature. The change in temperature of the water is a measure of the heat released or absorbed by the system.
The specific heat of water is 4.179 Joules per gram per degree Centigrade. The density of water is 1 gram per cubic centimeter, so one liter is 1000 grams. This means it takes 4179 Joules to raise one liter one degree Centigrade.

Water is something that will be affected if you raise the temperature. When cooking, you may need to raise the temperature of water to a boil, in order to cook food.
It is used to raise the temperature of the water.
It depends on what temperature is is at and how much water there is.
Depends on how high you want to raise the gram of water ;).
