What is heat fusion and heat of vaporization measures of?
The heat of fusion is the amount of heat (not temperature) required to change a solid to a liquid. It is also known as the melting point. The heat of vaporization is the amount of heat (not temperature) required to change a liquid to it's gaseous state. It is also know as it's boiling point.
What is a latent heat energy levels?
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
How does hydrogen change from one state of matter to another?
heat
What is latent heat of sublimation?
When a substance is below the triple point, the equilibrium will be between solid and vapor rather than solid/liquid or liquid/vapor. Sublimation is the direct change from solid to vapor without any intermediate phase change. The latent heat of sublimation is the energy required to change a given quantity of solid into the vapor at equilibrium. It is analogous to (but not the same as) latent heat of melting (energy required to melt the solid to liquid) and latent heat of vaporization (energy required to change a liquid into a gas).
What does the lantent heat of vaporization measure?
the amount of heat required to change the state from liquid to vapour of unit mass without changing the temperature
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 is the relationship of mass of an object to the amount of heat required to change its temperature?
The bigger he mass the more heatt required to change its temp.erature; Heat=m(T2-T1)
What is the relationship of mass an object to the amount of heat required to change its temperature?
The bigger he mass the more heatt required to change its temp.erature; Heat=m(T2-T1)
What special element must be present for element and compounds to change phase?
A change in internal energy, aka "heat transfer" either in or out of the material.
Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
What type of energy is required to change ice to water?

What is heat fusion and heat of vaporization measures of?
The heat of fusion is the amount of heat (not temperature) required to change a solid to a liquid. It is also known as the melting point. The heat of vaporization is the amount of heat (not temperature) required to change a liquid to it's gaseous state. It is also know as it's boiling point.
The amount of heat necessary to change a liquid to a solid at constant temperature?
None - heat is evolved, not required.
