Question

If the absolute temperature of a sample of an ideal gas is raised from $20^\circ	ext{C}$ to $40^\circ	ext{C}$, the average kinetic energy of its molecules changes by a precise factor of:

Prashant Kotian · Accepted Answer

Correct answer: B. The average translational kinetic energy of an ideal gas is directly proportional to its absolute temperature in Kelvin (). and . Therefore, the ratio .
