Question

The temperature at which the kinetic energy of oxygen molecules becomes double than its value at 27°C is

G1 Physics · Accepted Answer

Average translational kinetic energy of gas molecules is proportional to absolute temperature: K(avg) = (3/2)kT Initial temperature: T₁ = 27°C = 300 K To double kinetic energy: T₂ = 2T₁ = 600 K Convert back to Celsius: T₂ = 600 − 273 = 327°C Hence option C follows.
