Gravitational potential energy is the potential energy an object
has due to its position in a gravitational field. The higher an
object is the greater its gravitational potential. When it falls
the gravitational potential becomes kinetic energy.

Solids change their shapes in many ways. Solids will melt if
they are in hot temperatures, and this changes their shape.

Answer2:
As I learned it:
Matter can neither be created nor destroyed, only changed in form.
This is/was Newtonian physics. Einstein showed that in nuclear events matter can be changed to energy. And, in general relativity even more complex change can occur.
