Air moves from areas of higher temperature to areas of lower temperature. In this case, area X has the highest temperature (22ºC), while areas Y and Z both have a lower temperature (18ºC). Therefore, air will move from area X to area Y or area Z.
However, since the responses to choose from indicate directionality in moving from lower temperatures to higher, the correct answer here is:
area Y to area X
Air moves from area Y (18ºC) to area X (22ºC).
The statement that best explains the temperature difference is:
Warm air rises by convection to the upstairs.
This is because warm air is less dense and tends to rise, resulting in a higher temperature upstairs compared to downstairs.
The option that is an example of heat transfer by conduction is:
person getting warm from an electric blanket.
Conduction is the transfer of heat through direct contact between materials. In this case, the heat from the electric blanket is transferred directly to the person's body through contact.
The transfer of heat by direct contact is called conduction.
