In winter the air just above the top bunk of a bunk bed is warmer than the air just above the bottom bunk because warm air rises. Which of the following describes the method of heating that causes this difference in temperature?A radiation from the roomB heat transfer through the wallsC heat conduction through the bedD convection currents from the room

In which system is heat usually transferred from the cooler part to the warmer part?Select one:a.none of the above, because it is impossible to transfer heat in this mannerb.a refrigerator that is runningc.a stove as it heats up waterd.an electric fan that is running

Describe how convection helps in distributing heat in a room.

How does heat transfer occur?Question 4Select one:a.from cold to hot until the hot object becomes coldb.from hot to cold until both objects reach the same temperaturec.from cold to hot until both objects reach the same temperatured.from hot to cold until the cold object becomes hot

There are three main ways that heat can be transferred (conduction, convection, and radiation), but they do not all affect the building envelope.Group of answer choicesTrueFalse
