Question

The efficiency of a machine increases as the temperature inside _____ relative to the temperature outside.

Answer 1

The efficiency of a machine increases as the temperature inside increases relative to the temperature outside.

Answer 2

Answer:

The correct answer is increases.

Explanation:

According to the second principle of thermodynamics, when two objects at different temperatures come into thermal contact with each other, thermal energy always flows from the hottest object to the coldest.

Therefore we deduce that if the inside temperature of the machine is higher than the outside temperature, the machine will have a higher efficiency.
