Charles’ law is the formula that describes the link between temperature and volume (ABauer, R. 2018). Where volume and temperature are represented by V and T, respectively.
Example
Tire Pressure
Recently I was having my annual vehicle inspection that is required in most states. In the process, the mechanic and I were talking about the extremely low temperatures. Then he said that he has received several calls concerning low tire pressure signals from tire pressure monitoring devices being an issue. The onboard computer may generally be reset by simply adding air and raising the pressure. Sensor systems may be classified into two categories: direct systems, which measure tire pressure in the tire itself, and indirect systems, which measure tire rotational speed. The mechanic was unable to explain why the pressure was lower at low temperatures, despite knowing the answer. The relationship between temperature and pressure in an ideal gas was found by Jacques Charles.
Today, we understand that the pressure in a tire will increase in direct proportion to the temperature if the volume of air within the tire stays constant. In other words, if a tire is inflated to 35 PSI at 68 F (20 C) and the temperature decreases to 32 F (0 C), the tire pressure will decrease.
If pressure and gas mass are constant, the volume of an ideal gas equals its temperature (measured in Kelvin), i.e., the volume of the gas grows or decreases by the same amount as the temperature.
The following formula demonstrates this: V/T = k, where V is the gas’s volume, T is its temperature, and k is a fixed amount. Therefore, if the temperature falls significantly below the tire temperature, a warning will be sent.
