the relationship between kinetic energy and thermal energy is directly proportional
is the statement true or false
3 answers
The statement is generally true. The kinetic energy and thermal energy of a system are related. As the kinetic energy of the particles in a system increases, the thermal energy also increases. This relationship is often described as being directly proportional.

The substance has cooled down.
The substance has undergone a phase change.
The substance has evaporated.
The substance has gained kinetic energy.

Explain why the potential energy increases when ice starts to melt an becomes liquid water.
The particles form a more ordered structure, reducing potential energy.
The particles slow down, reducing kinetic energy.
The particles get closer together, reducing potential energy.
The particles gain kinetic energy, increasing their freedom to move.
