A Calorie is the amount of energy required to raise 1cm^3 of water. One cm^2 of water is a two-dimensional object so it technically does not exist.

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 does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
The kinetic energy of the particles in the liquid state is more than in the solid state comment?
If you freeze water you are removing a particle's kinetic energy from the system that is in the form of heat energy. So as you heat up ice you are giving the water molecules more thermal kinetic energy so it transitions to water. If you keep pumping in heat (energy) these molecules will eventually have so much energy it will vaporize and turn to steam.
Why does water not heat up or cool off as air?
because the specific heat of water is very high
How much heat energy is tranferred to hot water?
The specific heat of water is 4,186 J/g.K.

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 energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
A substance that can be burned to release heat energy?
Many substances can be burned to release heat energy, pretty much anything. However, water or ice is one that can not.
How much energy is consumed by water heat during washing?
consumed ya mum
How much energy flow is involved when changing a sample of water from a liquid to a gaseous?
google "water heat of vaporization"
How much energy has water got in IT?
Water has a specific heat of 1 calorie per gram per degreeC
How do you distinguish between temperature and heat give examples?
Temperature is the average amount of energy present in something; heat is the net total. For example, you can have a glass of water and a pool of water that are the same temperature: dispersed throughout, the amount of energy in each substance is the same. However, in total the pool as much more energy, or heat, because it is much larger than the glass of water.
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
Can you heat your water with a 9v battery?
Sure. But not much water, a 9 volt battery has very little power (energy).
