Question
What happens to the temperature of a gas when it is compressed?A.The temperature decreases.B.The temperature does not change.C.The temperature becomes unpredictable.D.The temperature increases.
Solution
D. The temperature increases.
When a gas is compressed, the molecules of the gas are forced closer together. This increases the frequency of collisions between the molecules, which in turn increases the kinetic energy of the molecules. Since temperature is a measure of the average kinetic energy of the molecules in a substance, the temperature of the gas increases as it is compressed.
