Question

Consider three identical flasks with different gases: Flask A: $CO$ at 760 torr and 273 K, Flask B: $N_2$ at 250 torr and 273 K, Flask C: $H_2$ at 100 torr and 273 K. In which flask will the molecules have the greatest average kinetic energy per mole?

Prashant Kotian · Accepted Answer

Correct answer: D. Average kinetic energy per mole of any gas depends only on absolute temperature (KE = 1.5 * R * T). Since all flasks are at 273 K, the kinetic energy is same in all .
