A container with the ability to expand and contract has its pressure changed from 5.0 atm to 7.5 atm at constant temperature. It the original volume was 4.0 L, what is the new volume?

2.667 L

Explanation:

We can solve this question using Boyle's Law of the ideal gas. When the temperature is constant, the volume is inversely proportional to the pressure of the gas. In the question, the pressure increases from 5 atm to 7.5atm. There is no change in temperature and the number of gas molecules. The calculation will be:

P1 * V1= P2 * V2

5 atm * 4 L = 7.5atm * V2

V2= 20L/7.5

V2= 2.667 L
