At 27 °C and 750 Torr,both a 16 g sample of methane gas (CH₄)and a 16 g sample of oxygen gas (O₂)will have the same: A)average molecular velocities B)average molecular kinetic energies C)number of gaseous particles D)total gaseous volumes E)average effusion rates

Question

Quizplus · Accepted Answer

The average molecular kinetic energies of gases are related to temperature and are independent of the particular gas. Thus, at the same temperature, all gases should have the same average kinetic energy. Therefore, both the 16 g sample of methane gas and the 16 g sample of oxygen gas will have the same average molecular kinetic energy at 27 °C and 750 Torr.

At 27 °C and 750 Torr,both a 16 G Sample
