Which of the following statements is TRUE?
A) At a given temperature, lighter gas particles travel more slowly than heavier gas particles.
B) The smaller a gas particle, the slower it will effuse.
C) The higher the temperature, the lower the average kinetic energy of the sample.
D) At low temperatures, intermolecular forces become important and the pressure of a gas will be lower than predicted by the ideal gas law.

Question

Quizplus · Accepted Answer

At low temperatures, intermolecular forces become important and the pressure of a gas will be lower than predicted by the ideal gas law. A is false because lighter gas particles move faster than heavier ones. B is false because smaller gas particles will effuse faster. C is false because the higher the temperature, the higher the average kinetic energy of the sample.
