Question

Compressing air to fill a scuba tank warms it up. A dive shop compensates by putting the tank in a tub of water, keeping the tank and the gas inside it at a constant temperature as it is filled.

Answer 1

W=Q.

Step-by-step explanation:

Considering the given information, initially, work done is greater than 0 and heat removed is less than 0. Then the work is applied by compressing the air. Since the temperature remains constant and no state-change has been mentioned therefore, internal energy also remains same. Hence, all the work done in compressing the gas is converted into heat removal. Hence, work done compressing the gas |W| equals the amount of heat removed |Q|.
