A)high pressure and high temperature
B)low pressure and high temperature
C)high pressure and low temperature
D)low pressure and low temperature
E)The density of helium is independent of pressure and temperature.

Question

Quizplus · Accepted Answer

According to the ideal gas law, density is inversely proportional to pressure and directly proportional to temperature when the number of gas molecules and the volume remain constant. Therefore, at low pressure and high temperature, the density of helium would be the smallest.
