When the temperature of a gas in a rigid container decreases, the particles of the gas move slower and experience fewer collisions with each other and the container walls. Because of this, it is sometimes necessary to add more air to automobile tires in the winter. Which gas law applies in this situation?

When the temperature of a gas within a rigid container decreases, the particles on average move more slowly and do not collide with one another or the container walls as often. It is the the ideal gas law that applies in this situation and states that a decrease in the temperature of a gas also results in a decrease in the pressure. Thus, automobile tyres which have a colder gas in the winter sometimes need additional air to provide suffiicient pressure.
