Evaporation uses energy to change from a liquid to a gas. Melting uses energy to change from a solid to a liquid. Condensation releases energy to change from a gas to a liquid. Freezing releases energy to change from a liquid to a solid.

What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
How do changes in energy and temperature influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
What is the temperature at which a solid changes to a liquid called is there a gain or a loss of energy?
this process is the process of gaining thermal energy. As any matter changes state from solid to any other form it will require energy. As energy is exerted on the solid perssure or electric or thermal or other type, the solid will obsorb the energy and change state. The solid thereby will in turn and at a ratio, increase the thermal energy it consumes.
What happens to molecular energy when a substance changes states?
The molecular energy will usually increase or decrease, depending on the exact situation.
What changes of state require energy?
Sublimation, melting, and vaporization are three changes of state which require energy.
What are changes of state that require energy?
Melting & evaporating.
What all changes of the state of matter require?
heat energy
What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
Does kinetic energy increase or decrease when a liquid changes to a gas?
the kinetic energy increases
What are the changes in the kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
When you increase energy in one form what happens to the energy in the other forms?
it changes form

How the energy of matter changes when it melts.?
When a solid melts, it is due to an increase in thermal energy to the temperature at which it melts.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
Which state changes require heat and which gives off heat?
Change from solid to liquid to gas require energy. Change from gas to liquid to solid emit energy.
