The ideal gas equation PV = nRT can be derived by combining which three laws?
A. Avogadro's, Dalton's, and Boyle's law
B. Boyle's, Graham's, and Dalton's law
C. Boyle's, Charles', and Avogadro's law
D. Charles', Graham's, and Gay-Lussac's law
Answer: Option C
Solution (By JKSSB Mock Tests)
Ideal gas equation: PV = nRT is obtained by combining Boyle's law (PV = constant at T,n), Charles' law (V ∝ T at P,n), and Avogadro's law (V ∝ n at P,T). Graham's law deals with diffusion, Dalton's with partial pressures. The constant R is the universal gas constant. For 1 mole, PV = RT. Real gases deviate at high pressure and low temperature.
