The ideal gas equation PV = nRT can be derived by combining which three laws?
A. Boyle's, Charles', and Avogadro's law
B. Charles', Graham's, and Gay-Lussac's law
C. Boyle's, Graham's, and Dalton's law
D. Avogadro's, Dalton's, and Boyle's law
Answer: Option A
Solution (By JKExamLibrary)
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.
