Question

how can you best describe the behavior of the particles when a substance is a gas? the particles are mostly vibrating in place with very little movement. the particles have a lot of energy and move around taking up as much space as possible. the particles are stationary with no movement at all. the particles have a little energy and are moving around but not spreading out to the entire container.

Explanation:

In a gas, particles have high kinetic energy. They move freely and rapidly, filling the entire available space as they are not strongly attracted to each other and can spread out to take up as much space as possible.

Answer:

The particles have a lot of energy and move around taking up as much space as possible.
