State whther each of the following will increase or decreases the total enegry content of the system:
a. Heat transferred to the surroundings
b. Work done on the system.
c. Work done by the system.

Text Solution

Verified by Experts

a. When heat is transferred to the surroundings, the total energy content of the system decreases. The system loses a part of energy in the form of heat.
b. When work is done on the system, the energy content of the system increases.
c. When work is done by the system, the energy content of the system decreases. The system does work at the cost of its energy.
