Question

arrange the steps in order to describe what happens to a gas when it cools. the particles of gas move slower. the gas changes to a liquid. the gas loses thermal energy. the space between the gas particles decreases.

Explanation:

When a gas cools, it first loses thermal energy. This causes the gas particles to move slower. As the particles move slower, the space between them decreases. Eventually, the gas changes to a liquid.

Answer:

1. The gas loses thermal energy.
2. The particles of gas move slower.
3. The space between the gas particles decreases.
4. The gas changes to a liquid.
