select the best answer for the question.

1. a heat pump can heat a building by

a. using solar energy to heat water and pumping it through the walls.
b. burning fuel to create heat and trapping it in the refrigerant.
c. creating heat from electrical resistance.
d. using refrigerant to transfer heat from the outside air to inside the building.

mark for review (will be highlighted on the review page)

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Heat pumps don't typically use solar energy to heat water for building heating in their standard operation.
• Option B: Heat pumps don't burn fuel to create heat; they transfer heat, unlike furnaces which burn fuel.
• Option C: Creating heat from electrical resistance is how electric resistance heaters work, not heat pumps.
• Option D: Heat pumps work by using a refrigerant to absorb heat from the outside air (even in cold weather, there is heat energy) and transfer it inside the building. This is the principle of a heat pump's operation (heat transfer, not heat creation).

Answer:

D. using refrigerant to transfer heat from the outside air to inside the building.
