QUESTION: find the pressure of a gas when its absolute temperature is 374k and its volume is 0.018m^3.
The universal law state that the volume of a given mass of an ideal gas varies directly with its pressure(pnm^2) a certain mass of a gas at an absolute temperature 275k and pressure 10^5Nm^-2 has a volume of 0.0225m3.
The General Gas Equation is;
P1*V1/T1 = P2*V2/T2
where we have
P1 = 10^5 Pa
V1 = 0.0225 m^3
T1 = 275 K
P2 = ?
V2 = 0.018 m^3
T2 = 374 K
Equating the two sets of values,
10^5 * 0.0225 / 275 = P2 * 0.018 / 374
P2 = 10^5 * (0.0225/0.018) * (374/275) = 1.7 * 10^5
P2 = 170 KPa
