which best explains how a heat pump can heat a room?\ncold air from the house is moved through pipes, where it absorbs thermal energy.\nwarm air from outside is pushed into the house to replace the cold air.\ncombustion warms the air when chemical energy is transferred to thermal energy.\nfuel is used to move a piston, which pushes warm air into the house.

Answer

Brief Explanations:

A heat - pump works by taking cold air from the house, moving it through pipes where it absorbs thermal energy from an external source (like the outside air or ground - source heat), and then returning the heated air to the house. The other options are incorrect as heat - pumps don't rely on warm air from outside being pushed in (it's about heat transfer not just air movement), combustion, or a piston - based fuel system for their operation.

Answer:

Cold air from the house is moved through pipes, where it absorbs thermal energy.
