The equation that relates pressure (P), volume (V), temperature (T), and the number of moles of gas (n) for an ideal gas is known as the ideal gas law. The ideal gas law equation is:
PV = nRT
Where: P is the pressure of the gas (in units such as Pascals, atmospheres, or torr). V is the volume occupied by the gas (in units such as cubic meters or liters). n is the number of moles of gas. R is the ideal gas constant, which has a value of 8.314 J/(mol·K) or 0.0821 L·atm/(mol·K), depending on the units used. T is the temperature of the gas (in Kelvin).
This equation allows you to calculate the pressure exerted by an ideal gas at different temperatures as long as you know the other variables (volume, number of moles, and gas constant).
