Thermal Energy Transfer Quick Check

Answer 1

GACA Physical Science Thermal Energy Quick Check Answers

1. As the substance’s thermal energy increases, the kinetic energy of its particles increases, and vice versa.

2.Its molecules move around more quickly, so there is more space between them, making it less dense than the air above it.

3.Warmer sauce at the bottom of the pot is less dense, so it rises, forcing cooler sauce down, where it is warmed

4.Hot soup warms the bowl where it sits

5. Transfer of thermal energy through infrared waves

Answer 4

What is your question about thermal energy transfer?

Answer 5

area Y to area X.

Answer 6

I apologize for the error in my previous response. The correct answer is:

Air will move from area X to area Z.

Air moves from an area of high pressure to an area of low pressure. In this case, area X has a higher temperature than areas Y and Z. The warmer air in area X is less dense and rises, creating an area of low pressure. Cooler air from areas Y and Z will then move toward the area of low pressure, which is area X. Therefore, air will move from area Z to area X.
