Question

Which of these expressions are correct variations of the Combined Gas Law?

Answer 1

Answer:

Both

Explanation:

The combined gas law is also known as the general gas law.

From the ideal gas law we assume that n = 1;

So;

              PV  = nRT

 and then;

                  $\frac{P_{1}V_{1} }{T_{1} }$  = $\frac{P_{2}V_{2} }{T_{2} }$

   If we cross multiply;

                P₁V₁T₂   = P₂V₂T₁

  So;

         T₁ = $T_{2} \frac{P_{1}V_{1} }{P_{2} V_{2} }$

Also;

         V₂  = $V_{1} \frac{P_{1} T_{2} }{P_{2} T_{1} }$

So from the choices both are correct
