Question

Which of the following changes would increase the pressure of a gas if moles are held constant?

A. Part of the gas is removed

B. The temperature is decreased

C. Nothing is changed

D. The container size is decreased

Answer 1

D. volume is inversely related to pressure

Answer 2

The correct answer is option D. The container size is decreased.

Step-by-step explanation:

Hello!

Let's solve this!

The formula used in gases is PV = nRT

If we clear the pressure:

P = nRT / V

This indicates an inversely proportional relationship between volume and pressure. So if I need to increase the pressure, I need to decrease the volume or vice versa.

After analysis, the correct answer is option D. The container size is decreased, which indicates a decrease in volume.
