Work Done in Gaseous System – Rankers Physics

Thermodynamics: Practice Problem & Solution

110 J of heat is added to a gaseous system whose internal energy is increased by 40 J then amount of external work done is
150 J
70 J
110 J
40 J

Solution Explained:

To solve this problem, we apply the core principles of Thermodynamics. Understanding the underlying formula is key to arriving at the correct answer below:

According to the first law of thermodynamics, \(\Delta Q = \Delta U + W\). Substituting the values, \(110\text{ J} = 40\text{ J} + W \Rightarrow W = 70\text{ J}\).
