Molecules in a solid are tightly packed together and therefore have very low average kinetic energy. However, if you add energy to the system you are increasing the random motion of molecules and the intermolecular distance within the molecules increases thereby changing the substance into a liquid state. Same is true when going from liquid to gaseous state of matter. So only the liquid to gas phase change could occur, if all other conditions remain the same.
Liquid to a gas
When the molecules in a body move with increased speed, it's possible that the body will change from a
Liquid to gas
As the molecules in a body move with increased speed, i.e. increasing kinetic energy, it is possible that the body will change from the solid phase to the liquid phase, or the liquid phase to the gas phase, and in some cases from the solid directly to the gas phase.
Only one phase change of the four is possible, that of a liquid to a gas. Increased molecular energy is related to dissociative phase changes : solid to liquid / liquid to gas.

That could cause a change from solid to liquid, or from liquid to gas.
they get heated up and evaporate
The molecules begin to release and move into the air more quickly than they condense back into liquid.
A gas is most likely to change to the liquid phase when the pressure on the gas is increased. This is because the same number of molecules will have less space to occupy.
no, but the molecules spread out. so it appears the mass has increased, but it hasn't.
