On a hot summer day, you turn the thermostat in your house way down. Assume that your house is well sealed and that no air enters or leaves the house. When the air temperature in your house falls a short while later, what statement is correct regarding the air pressure?

Question

Quizplus · Accepted Answer

When the air temperature in your house falls, the air molecules lose kinetic energy and move slower, resulting in a decrease in air pressure. This happens because the air molecules are not colliding with the walls of the house with as much force as they were when they had higher kinetic energy at the higher temperature. Therefore, the correct statement is that the air pressure is lower at the lower temperature.
