Question

The First Law of Thermodynamics is essentially a statement of conservation of energy. It involves changes in internal energy, the heat flowing into the system and the work done by the system. When heat flows into the system, the internal energy of the system increases. When positive work is done by the system, the system loses internal energy.

As an example, if a balloon (our system) expands it does positive work on its surroundings (the air surrounding the balloon and the rest of the universe). Suppose in the process of expanding the balloon does +2.74

Explanation / Answer

(1). The work done by the surroundings on the balloon = - 2.74 x 10 -3 J

2. Work done W = +2.74
