Question

compared to the particles in a liquid lava sample, the particles in a hardened lava sample
a are moving more slowly
b have a higher temperature
c have more kinetic energy
d are farther apart

Explanation:

In a solid (hardened lava), particles have less kinetic energy and move more slowly compared to particles in a liquid (liquid lava). Temperature and kinetic - energy are related, and particles in a liquid are generally farther apart than in a solid.

Answer:

A. are moving more slowly
