Question

In a refrigerator, energy is used to make thermal energy flow from the inside of the refrigerator to the outside. Use a law of thermodynamics to explain why thermal energy will not move in this direction naturally.

Answer 1

Explanation:

According to the Second Law of Thermodynamics, heat will always flow spontaneously from hot to cold, and never the other way around. A refrigerator causes heat to flow from cold to hot by inputting work, which cools the space inside the refrigerator. thermal energy is transferred from the cool air inside the refrigerator to the warmer air in the kitchen. ... As a liquid, the refrigerant absorbs thermal energy from the cool air inside the refrigerator and changes to a gas.
