Its molecules move around more slowly, so there is more space between them, making it less dense than the air above it.
Its molecules move around more quickly, so there is more space between them, making it less dense than the air above it
Its molecules move around more quickly, so there is more space between them, reducing its mass.
Why does air in a room rise when it gains thermal energy from a heater? (1 point)
O Warm air always rises.
1 answer
When air in a room gains thermal energy from a heater, its molecules absorb the heat energy and begin to move around more quickly, increasing the space between the molecules of air. This causes the air to become less dense than the surrounding air, so it rises above the denser air. Thus, warm air in a room rises due to convection currents that are created as a result of temperature differences.
