Question

BRAINLIESTTT ASAP!! PLEASE HELP ME :) How is molecular motion related to phase changes?

Answer 1

When a substance gains heat, its molecules move more vigorously. When a substance loses heat, its molecular action decreases.

Conceptually and quantitatively, flow of energy during change of state effects motion of atoms and molecules in chemical and physical processes.

Phase change -

Now, the motion of a molecule can be increased by the following;

- Adding heat through a temperature difference

- The absorption of one of the five forms of energy

- Temperature increases according to specific heat of the substance

Answer 2

All phase changes either have an increase or decrease of Intermolecular forces involved.
