A BTU is defined as the amount of heat required to raise the temperature of one pound of liquid water by one degree Fahrenheit. Melting a pound of ice at 32 °F requires 143 BTU. As is the case with the calorie, several different definitions of the BTU exist, which are based on different water temperatures and therefore vary by up to 0.5%:

What happens to latent heat when ice thaws?
its absorbed
What information does the latent heat of fusion give?
latent heat of fusion tells us about the amount of energy that must be taken off from water at 00C to fuse it into ice at 00C . Actually this in this phase temperature remains constant and this energy is (either latent heat of fusion or latent heat of vaporization is the potential energy which is possessed by the states by their virtue.
What is the value of the latent heat of fusion of ice in British English system of units?

Can latent heat be zero?
No, latent heat can never be zero.Because latent heat is the hidden heat so there has to be heat more than zero.
Heat that causes a substance to change form is called?
latent heat :)
What are the applications of latent heat of fusion and latent heat of vapourisation?
the application of latent heat fo fussion is ice is used to put in drinks to make cool because ice has hih specific heat capcity
What kind of heat is demonstrated when ice melts?
latent heat
What happens to latent heat when ice thaws?
its absorbed
Why in ice cube at 0 degree Celsius is much effective in cooling a drink that the same mass of water at 0 degree Celsius what is the formula?
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.
How do you define latent heat and What is its relationship to potential energy?
Latent heat is the heat required to achieve a change of phase - for example, to melt ice and convert it to water. As to the relationship with potential energy, latent heat IS a type of potential energy.
What happens to the heat when water solidifies into ice it absorbed or evolved?
I think it is evolved because if the heat is absorbed then the latent heat will be given to the matter( ice) then the ice will start melting
How latent heat is an important source of atmospheric energy?
In the atmosphere latent heat is a property of water vapour. When water vapour condenses it releases latent heat, and latent heat must be supplied to evaporate liquid water. This heat affects the behaviour of the weather. Similar effects occur in the change from liquid water to ice and vice versa.
Why does the ice cream feel cooler to the teeth than the ice cold water?
Ice cream feels cooler to our teeth than ice cold water because during the change of state some amount of heat is absorbed which is known as Latent Heat. So in ice no hidden heat is absorbed while in cool water latent heat of fusion or melting is absorbed.
Why does ice cream appear cooler to teeth than ice cold water?
Ice cream feels cooler to our teeth than ice cold water because during the change of state some amount of heat is absorbed which is known as Latent Heat. So in ice no hidden heat is absorbed while in cool water latent heat of fusion or melting is absorbed.

What is the value for the latent heat of fusion of ice?
First you need to know at what temp. is the ice?The latent heat of fusion for ice at 32 degrees F is 144 but per pound.This will change 1 pound of ice at 32 degrees F into water at 32 degrees F.It is defined as the amount of heat required for the 1 mole of ice to bring a change in its state, that is, from solid state to liquid state. It is also known as enthalpy of fusion, specific melting point or latent heat of fusion of ice. The particular temperature at which there is a change in the state of the ice is known as the melting point of ice.
