The gas law that describes the relationship between the pressure (P), volume (V), and temperature (T) of a gas is known as the Ideal Gas Law. The Ideal Gas Law states that:
PV = nRT
where P is the pressure of the gas, V is its volume, n is the number of moles of gas, R is the gas constant, and T is the temperature of the gas.
When a car tire is filled with air, its pressure is determined by the amount of air in the tire and the temperature of the air. During the winter season, the temperature of the air inside the tire decreases. According to the Ideal Gas Law, if the temperature of a gas decreases, its pressure decreases as well, assuming the volume of the gas remains constant.
Therefore, during the winter season, the pressure of the air inside the tire decreases, which can lead to underinflated tires. Conversely, during the summer season, the temperature of the air inside the tire increases. According to the Ideal Gas Law, if the temperature of a gas increases, its pressure increases as well, assuming the volume of the gas remains constant.
Therefore, during the summer season, the pressure of the air inside the tire increases, which can lead to overinflated tires. This is why it is important to check the pressure of car tires regularly and adjust it as needed depending on the season.
