What do you call heat that is added or removed from a substance but does not change the state of the substance sensible heat latent heat super heat or radiation heat?
Latent Heat.
What is the heat that is released when water condenses and changes to liquid form?
The latent heat of vaporisation.
How do solids and liquids change state?
they change their state by absorbing heat known as latent heat. There is no temperature change in a substance she they change their state because the heat is used to break the intermolecular bonds between the molecule.
What type of energy is absorbed or released when a substance changes phase?
pChanges in bonding arrangements between atoms and molecules result in absorption or release of heat (called latent heat). For example when water freezes, some heat is extracted to the environment, and the temperature does not fall until all is frozen. After that further removal of heat causes the temperature to fall below freezing point.
What does the heat latent heat of vaporization measure?
The energy required to boil a substance

Latent Heat.
Heat that causes a substance to change form is called?
latent heat :)
What is the difference between latent heat of fusion and latent heat of vapourization?
the heat which is absorbed by a substance for changing solid into liquid state by keeping temperature constant is called latent heat of fusion while the heat which is evolved during phase change of liquid to vapour state at constant temperature is called latent heat of vapourization
What is the difference in specefic heat and latent heat?
Specific heat is the heat energy in joules required to rise the temperature of one kg of substance through one kelvin without a change in its state. But latent heat is the heat required to change the state of one kg of substance without change in temperature.
What are two changes of state for water that cause latent heat to be released?
liquid and gas
What is the heat that is released when water condenses and changes to liquid form?
The latent heat of vaporisation.
What is specific latent heat.?
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
Why is latent heat called hidden heat?
The latent heat of fusion refers to the heat of fusion in reactions that involve a solid that forms a liquid, or vice versa. The latent heat of vaporization is the latent heat involving a liquid that forms a gas or vice versa.Latent means hidden or unseen. In this context, the 'latent' heat is the heat that is not detectable as a temperature change in the substance. Rather than adding kinetic energy (which is detectable as a temperature change) some heat is required to break the bonds of the solid structure.
What is the relationship between energy and phase changes?
Adding or removing energy in the form of heat causes the phase change. The amount of heat to be added or removed is called latent heat. It changes the state of a substance without changing it's temperature. There are two types of latent heat. The latent heat of fusion, and the latent heat of vaporization. The latent heat of fusion must be added to change phase from solid to liquid, and removed to change from liquid to solid. The first change is endothermic and the second change is exothermic. The latent heat of vaporization must be added to change phase from liquid to vapor, and removed to change from vapor to liquid. Again the first change is endothermic and the second change is exothermic.
What does latent heat of fusion represents?
The amount of heat energy required to solid substance solid into a liquid state without any changes in temperature ______________________ Apex: The amount of energy required to turn a mole of a solid into a liquid
What is the difference of heat capacity and latent heat?
Specific heat capacity (equation Q=mc��T) is the measure of the energy required in Joules to raise 1kg of a substance by 1.0 K (numerically equivalent to 1 C)Whereas, specific latent heat (equation Q=mL) is the amount of energy needed to change to the state of a substance either from solid to liquid, liquid to gas without changing its temperature.
How can the temperature of a substance remain the same even if the substance is absorbing thermal enerrgy?
This is because of latent heat. Thermal energy is stored in object in form of latent heat.
