How much heat is needed to convert 150 g of ice to water?
41,800
If 30.86g of H2O is frozen (from liquid to solid) how much heat energy is required?
No heat (energy) is required to freeze water (from liquid to solid). Freezing RELEASES energy (heat), as it is an exothermic event. If you want to know how much energy is release, you need to know the heat of fusion for water, and then multiply that by the mass of water being frozen.
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
How much heat energy is needed to vaporize g of water at its boiling point of K?
1oo calories for 1 g
Do you water plants after a freeze?
You can water plants after a freeze, but it is much more important to make sure they are well-watered before the freeze. Most tissue damage occurs because of a lack of water inside the tissues, which then lose the heat energy from inside the cells (and the cells rupture when they freeze).
Why does water take so long to warm up?
The specific heat of water determines how much energy is needed to heat water.
How much heat requires one litre of water evaporates?
The needed heat is 2 258 kJ.

How much coolant aka water is needed for a nuclear power station?
It depends on how much it needs to be cooled down, or transferred. The more heat there is the more coolant (water) is needed.

How much energy to burn a calorie?
A calorie is the amount of energy needed to heat 1 gram of water by 1 degree Celsius. So you can't burn a calorie.
How much heat is in fresh water?
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.
How much heat is needed to raise kg of water from 4 degrees Celsius to 83 degrees Celsius?
2,641,760J...
How much heat is needed to heat 100g of water from 10 to 95 degrees?
A calorie of energy (NOT to be confused with a Calorie, they are different so watch the caps) is the amount necessary to heat 1 gram of water 1oC, so 30 calories are needed to heat 30 g of water 1 degree. To heat it 70oC would take 2100 calories (or 2.1 Calories) of energy.
How much heat energy is needed to vaporize g of water at its boiling point of K?
1oo calories for 1 g
How much heat is needed to raise 8 kg of water from 4 degrees Celsius to 83 degrees Celsius?
2,641,760J...
