Explanation The average kinetic energy of molecules of a gas is directly proportional to its temperature. Thus, as the temperature increases, the average kinetic energy also increases. When the average kinetic energy is twice of that of room temperature, then the corresponding temperature also will be twice of the room temperature. Here, the room temperature is given as 20 °C and hence the temperature at which gas molecules will have the twice the kinetic energy of its value at room temperature, 20 °C is 40 °C . Conclusion: Since the average kinetic energy of molecules of gas is directly proportional to the temperature, the temperature at which the gas molecules have twice the average kinetic energy they have at room temperature, 20 °C is 40 °C

Kinetic Theory of Gas

The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all dire…
