Science 8 Q1 / Properties of Matter

As thermal energy increases, there is less particle movement.
As thermal energy increases, particle movement does not change.
As thermal energy increases, it is not possible to predict particle movement.
As thermal energy increases, there is more particle movemen

Answer 1

t.

This is because thermal energy is a measure of the kinetic energy (movement) of particles in a substance. As thermal energy increases, the particles gain more energy and therefore move faster.
