Heat Transfer and Temperature

• The atoms/molecules themselves expand in size
• The temperature decreases as the atoms/molecules slow down
• The atoms/molecules gain energy and move faster (correct)
• The atoms/molecules lose energy and move slower

• The volume decreases as the atoms/molecules get closer together (correct)
• The volume increases as the atoms/molecules gain energy and move faster
• The volume increases as the atoms/molecules spread further apart
• The volume remains constant as cooling does not affect the gas

• They remain stationary and do not travel at all
• They travel in circular patterns until they collide with each other
• They travel in straight lines until they collide with each other or an object (correct)
• They travel in random directions, never colliding with each other
