Question

how would you best describe the particles in a gas?
they have a lot of energy and are tightly packed.
they have low energy and are very spread out.
they have a lot of energy and are very spread out.
they have low energy and are tightly packed.

Explanation:

In a gas, particles have high kinetic energy (a lot of energy) as they move freely. Also, gas particles are not closely held together like in solids (not tightly packed) but are very spread out as there are weak intermolecular forces between them.

Answer:

They have a lot of energy and are very spread out.
