Question

What is the combined gas law?

Answer 1

For a given quantity of gas, `(P_1V_1)/T_1 = (P_2V_2)/T_2`

Explanation:

Of course, when `P_1 =P_2`, we get Charles' Law, `V_1/T_1 = V_2/T_2`. And when `T_1=T_2`, we get Boyle's law, `P_1V_1 = P_2V_2`. Combining the two laws, we get `PV` `=` `k`. Once we introduce `n`, the molar quantity of gas, and a suitable constant, we get the Ideal Gas Law.
