Question

11.Use the particle theory of matter to explain what happens to the particles when an ice

cube melts and the water it produces evaporates. [3]

​

Answer 1

l

Solid to Liquid Particles

The solid ice particles absorb heat energy from the warmer air, giving the particles energy and enabling them to move away from one another. Liquid particles still touch each other, but they are further apart than solid particles.

Answer 2

Explanation:

The solid ice particles absorb heat energy from the warmer air, giving the particles energy and enabling them to move away from one another. Liquid particles still touch each other, but they are further apart than solid particles. ... This is what happens when the ice cube (a solid) turns into water (a liquid).
