Heat transfer

What is the primary driving force behind heat transfer?

• Difference in pressure

• Difference in velocity

• Difference in temperature

• Difference in material density

Which property of a material is crucial for slowing down heat transfer by conduction?

• High thermal conductivity

• Low thermal conductivity

• High density

• Low density

How do double-pane windows help reduce heat transfer by convection?

• They increase the thermal conductivity of the glass.

• They trap air between the panes, preventing significant air movement.

• They reflect all incoming radiation.

• They create a vacuum between the panes, eliminating all heat transfer.
