Question

Why does warm air rise?


- molecules spread apart, move faster and become less dense


- molecules move closer together, move slower and become more dense

Answer 1

so the answer is?

Answer 2

choose from these
- molecules spread apart, move faster and become less dense


- molecules move closer together, move slower and become more dense

Answer 3

When air is heated, the molecules spread apart and move faster, which decreases the density of the air. This less dense warm air is then pushed up by the denser, cooler air surrounding it. This is because hotter air is lighter and less dense than cooler air, so it rises above the cooler, denser air. This is known as convection, where warmer air rises and cooler air sinks.

Answer 4

Warm air rises because it is less dense than cooler air.

Answer 5

molecules spread apart, move faster and become less dense
