Question

A gas expands from 15 L to 39 L. In the process it performs 1.8 kJ of work. For which type of change can

the initial and final pressure of the gas be calculated?

Answer 1

An isothermal process (change)

Step-by-step explanation:

The initial volume of the gas, V₁ = 15 L

The initial volume of the gas, V₂ = 39 L

The amount of work it performs, W = 1.8 kJ

For the above change, the initial and final pressure of the gas can be calculated, using Boyle's law which is based on an isothermal change process as follows;

P₁·V₁ = P₂·V₂

P ∝ 1/T
