Final answer:
Heat transfer and work both involve the transfer of energy.
Step-by-step explanation:
Heat transfer (Q) and work (W) both involve the transfer of energy.
Heat transfer is the transfer of energy due to a difference in temperature. For example, when the sun warms the air in a bicycle tire, the heat transfer increases the temperature of the air.
Work involves the exertion of a force through a distance. For example, when a bicyclist pumps air into the tire, work is done on the system, which also increases the temperature.
