## Quote from Britannica

Gas laws, Laws that relate the pressure, volume, and temperature of a gas. Boyle’s law—named for Robert Boyle—states that, at constant temperature, the pressure P of a gas varies inversely with its volume V, or PV = k, where k is a constant. Charles’s law—named for J.-A.-C. Charles (1746–1823)—states that, at constant pressure, the volume V of a gas is directly proportional to its absolute (Kelvin) temperature T, or V/T = k. These two laws can be combined to form 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. Though this law describes the behaviour of an ideal gas, it closely approximates the behaviour of real gases. See also Joseph Gay-Lussac.

- Enter ${n}_{y}$ values up to 'y' by using comma instead of space.

* If,

* ${n}_{a}$ = 2

* ${n}_{b}$ = 1.83

* ${n}_{c}$ = 3.05

* Enter 'y' = 3;

* ${n}_{y}$ = 2,1.83,3.05
