Z 18
Air will move from ____.
area Z to area Y
area X to area Z
area Y to area Z
area Y to area X
Air will move from area X to area Z.
Which type of energy transfer is shown in the picture?
conduction
density
convection
radiation
Without the presence of a picture, it is not possible to determine which type of energy transfer is being depicted. Please provide more information or context about the picture.
Area Temperature (*C)
downstairs 22
upstairs 26
Based on the given information, the type of energy transfer depicted is likely convection. As the air upstairs is at a higher temperature (26°C) compared to downstairs (22°C), the warmer air rises and circulates, transferring heat from the upstairs area to the downstairs area through the process of convection.

Which statement best explains the temperature difference?
Energy is transferred between the areas when the molecules touch.
Energy from the cooler air is transferred upstairs.
Warm air rises by convection to the upstairs.
The cooler air downstairs loses energy to the enviroment.
The statement "Warm air rises by convection to the upstairs" best explains the temperature difference. As warm air is less dense than cool air, it rises by convection from the downstairs area to the upstairs area, resulting in a temperature difference.
Which option is an example of heat transfer by conduction?
pavement heating up in the sun
air conditioner cooling the room
person getting warm from an electric blanket
air getting warm from a radiator
An example of heat transfer by conduction is air getting warm from a radiator.
The transfer of heat by direct contact is called _____
kinetic energy.
radiation.
vibrating molecules.
conduction.
