Question

Relate the changes in molecular motion of particles as they change from solid to liquid to gas.

Answer 1

Answer:

here is you answer mate...

Explanation:

1.Solid to Liquid --When a solid is heated the particles gain energy and start to vibrate faster and faster. ... Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.

2.Liquid to Gas--Vaporization occurs when a substance changes from a liquid to a gas. The molecules in a liquid are in constant motion while staying relatively close together due to intermolecular forces. When an increase in temperature occurs, the molecules' kinetic energy also increases.

Answer 2

Answer:

As the phase changes occur, the freedom of motion of the particles increases.
