A) decrease by half
B) increase by a factor of 1.27
C) increase by a factor of 100
D) double
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 the temperatures to Kelvin (373 K and 473 K), the ratio of the final to initial temperature is 473/373, which is approximately 1.27.

According to Kinetic- Molecular Theory, If the Temperature of a Gas
