The pressure of the gas inside a rigid, sealed container decreases when it is placed in a freezer. This is caused by a change in the average speed of the gas particles and a change in the temperature of the gas inside the container.
Which of the following describes the changes associated with this decrease in gas pressure?
Average speed of the gas particles decreases; Temperature of the gas decreases
Average speed of the gas particles decreases; Temperature of the gas increases
Average speed of the gas particles increases; Temperature of the gas decreases
Average speed of the gas particles increases; Temperature of the gas increases
