Why does air in a room rise when it gains thermal energy from a heater? (1 point)
Its molecules move around more quickly, so there is more space between them, reducing its mass
Its molecules move around more slowly, so there is more space between them, making it less dense than the air above it Warm air always rises.
O Its molecules move around more quickly, so there is more space between them, making it less dense than the air above it

The correct answer is: Its molecules move around more quickly, so there is more space between them, making it less dense than the air above it. When air is heated, its molecules gain thermal energy and move faster, causing them to spread out and occupy more space. This makes the air less dense than the surrounding cooler air, causing it to rise upward due to the force of buoyancy.
here are the answers to the quick check.
1: As the substance’s thermal energy increases, the kinetic energy of its particles increases, and vice versa.
2: Its molecules move around more quickly, so there is more space between them, making it less dense than the air above it.
3: Warmer sauce at the bottom of the pot is less dense, so it rises, forcing cooler sauce down, where it is warmed.
4: Hot soup warms the bowl where it sits.
5: transfer of thermal energy through infrared waves

6: Conduction is the transfer of thermal energy through direct contact of two materials.
7: Radiation is the transfer of thermal energy through electromagnetic waves.
8: Convection is the transfer of thermal energy through the movement of fluids or gases due to differences in temperature.
