Question

Temperature (°C)
downstairs
22
upstairs
26
Which statement best explains the temperature difference?
(1 point)
• The cooler air downstairs loses energy to the environment.
• Energy is transferred between the
areas when the molecules touch.
• Warm air rises by convection to the upstairs.
• Energy from the cooler air is transferred upstairs.

Answer 1

The statement that best explains the temperature difference is:

• Warm air rises by convection to the upstairs.

This accurately describes the process by which warmer air, being less dense, moves upward, resulting in a higher temperature upstairs compared to downstairs.
