According to kinetic-molecular theory,if the temperature of a gas is raised from 100 °C to 200 °C,the average kinetic energy of the gas will ________.
A)double
B)increase by a factor of 1.27
C)increase by a factor of 100
D)decrease by half
E)decrease by a factor of 100

Question

Quizplus · Accepted Answer

The average kinetic energy of a gas is proportional to its temperature in Kelvin. Converting 100 °C to Kelvin gives 373 K and 200 °C gives 473 K. The ratio of 473/373 is approximately 1.27, so the kinetic energy increases by a factor of 1.27.
