Q:

Which law relates to the ideal gas law?

A) P1T1 = P2T2 B) P1/V1 = P2/V2
C) P1V1 = P2V2 D) T1/V1 = T2/V2
 
Answer & Explanation Answer: C) P1V1 = P2V2

Explanation:

Ideal Gas Law ::

The Combined gas law or General Gas Equation is obtained by combining Boyle's Law, Charles' Law, and Gay-Lussac's Law. It shows the relationship between the pressure, volume, and temperature for a fixed mass (quantity) of gas:

P1V1T1 = P2V2T2

 

Hence, the Boyle's law P1V1 = P2T2, relates to ideal gas equation.
