Question

Law of conservation of mechanical energy can be applied to a non-isolated system.

• A. True
• B. False

Answer 1

The correct option is B False

1. An isolated system means the energy produced in the process cannot exchange its energy outside the boundary. Whereas, a non-isolated system shares the energy outside the boundary.
2. According to the principle of conservation of energy, the total energy of the system remains constant. There is no exchange of heat to the surroundings. Therefore, it cannot be applied to a non-isolated system.

Hence, the given statement is False.
