Answer 1

Warm air rises primarily because it is less dense than cooler air. As air is heated, the molecules move faster and spread apart, resulting in a decrease in density. This lower density causes the warm air to rise, as it is buoyant compared to the denser, cooler air surrounding it. Therefore, the correct answer is:

**Warm air is less dense than cooler air.**
