What happens to the energy transferred in a heat pump when it operates?.
- A.Energy is conserved and transferred from a low to a high temperature.
- B.Energy is lost as heat to the surroundings.
- C.Energy is created to maintain temperature differences.
- D.Energy is only transferred when the system is in equilibrium.
Model answer
What a good answer should say
- Energy is conserved and transferred from a low to a high temperature.
Explanation
Why this works
In a heat pump, energy is conserved as it transfers thermal energy from a lower temperature source to a higher temperature area, which is a key principle in thermodynamics.
