Question

The picture below shows the heat transfer that occurs in a house as the air circulates in a room. Which thermal energy transfer process is responsible heating up the room. aconvection because it causes the warmer air to rise up and the cooler more dense air to sink to the bottom. bradiation because it causes thermal energy to transfer through direct contact of the air particles cconduction because it causes the heat to transfer through the electromagnetic waves into the sky. dconduction because it causes warmer air to rise up and the cooler more dense air to sink to the ground.

Answer 1

The correct answer is a) convection because it causes the warmer air to rise up and the cooler, more dense air to sink to the bottom.

Convection is the primary thermal energy transfer process in fluids (like air) where warmer, less dense air rises, and cooler, denser air sinks, leading to the circulation of air that helps heat up a room.
