The Ideal Gas Law — Unit test

Question 11 • LA-Chemistry A

The volume of a gas decreases to half of its original volume, but the gas maintains the same number of moles and temperature. According to the ideal gas law, what will most likely happen to the pressure?

Answer
A
It will double.
B
It will decrease.
C
It will increase slightly.
D
It will remain the same.

Explanation

The ideal gas law is PV = nRT. Since the number of moles and temperature stay constant, pressure is inversely proportional to volume. Halving the volume therefore doubles the pressure, so the correct choice is “It will double.”
