Question

A sample of helium gas is

sealed in a container with a lid
that can be moved up and down.

Select all of the following that will result in an increase in pressure inside the container.

A. Decreasing volume

B. Increasing volume

C. Decreasing temperature

D. Increasing temperature

E. Adding one more mole of helium gas

F. Removing one mole of helium gas

Answer 1

P=nRT/V

P ≈ 1/V = decreasing volume

P ≈ T = increasing temperature

P ≈ n = adding one more mole of helium
