Question 5

Which statement best compares conduction, convection, and radiation?

Revolt · Accepted Answer

Convection and conduction transfer thermal energy through matter only, and radiation transfers thermal energy through both matter and empty space.

Question 9

Identify the method of thermal energy transfer at work in hot air balloons. Explain how thermal energy is transferred in this scenario.

Revolt · Accepted Answer

The method of thermal energy transfer at work in hot air balloons is convection. The air inside the balloon is heated, causing the molecules to move faster and spread out. This makes the hot air less dense than the cooler air surrounding it, which causes the hot air to rise and lift the balloon.

Question 10

Identify the method of thermal energy transfer.

Revolt · Accepted Answer

radiation; A:: convection; B:: radiation; C:: conduction
