As the pressure in an ideal gas is increased isothermally the average molecular speed:
A)increases
B)decreases
C)increases at high temperature, decreases at low
D)decreases at high temperature, increases at low
E)stays the same

Question

Quizplus · Accepted Answer

The average molecular speed in an ideal gas is determined by its temperature, according to the kinetic theory of gases. Since the process is isothermal (temperature is constant), the average molecular speed remains the same regardless of changes in pressure.
