These two laws can be combined to form the ideal gas law a single generalization of the behaviour of gases known as an equation of state PV nRT where n is the number of gram-moles of a gas and R is called the universal gas constant. The Ideal Gas Law. The ideal gas law also called the general gas equation is the equation of state of a hypothetical ideal gasIt is a good approximation of the behavior of many gases under many conditions although it has several limitations.
Because the units of the gas constant are given using atmospheres moles and Kelvin its important to make sure you convert values given in other temperature or pressure scales.
In 1662 Robert Boyle discovered the correlation between Pressure P and Volume V assuming Temperature T and Amount of Gas n remain constant. The law shows the relationship between temperature volume and pressure for a fixed quantity of gas. Two cubic feet of a gas at 75 psig and 80F are compressed to a volume of 1 cubic foot and then heated to a temperature of 300F. T 2 x 10 5 5x 10 -3 05 831 T 2406 x 10 2 K.
