Question

What happens to the particles of a solid when the solid changes into a liquid? (5 points) a They increase in size. b They decrease in size. c The attractive force between them increases. d The attractive force between them decreases.

Answer 1

The answer is D, the attractive force between them decreases.

Although the volume that the particles take up generally increases when going from solid to liquid, particles themselves never change their size. It’s the attractive force that decreases and doesn’t pull the particles together as tightly when a solid changes to liquid.
