Determine why gases rise when they are heated. The particles lose kinetic energy and move closer togetherThe particles gain kinetic energy and move further apartSome of the particles are destroyed so the gas gets lighterThe particles get smaller and lose weight

The correct answer is: The particles gain kinetic energy and move further apart.

Here's why:

1. When gases are heated, the particles (atoms or molecules) that make up the gas absorb this heat energy.

2. This absorbed heat energy is converted into kinetic energy, causing the particles to move faster.

3. As the particles move faster, they tend to move further apart from each other. This is because the increased kinetic energy overcomes the intermolecular forces that would otherwise keep the particles closer together.

4. As the particles move further apart, the gas expands and its density decreases.

5. Since density is mass divided by volume, a decrease in density means the gas is less dense than the surrounding cooler gas or air.

6. As a result, the heated, less dense gas rises through the cooler, denser gas or air. This is due to the principle of buoyancy, which states that less dense materials will rise above more dense materials when subjected to a gravitational force.

So, the statement "The particles gain kinetic energy and move further apart" is the correct explanation for why gases rise when they are heated.
