Question 28
28. The pressure and absolute temperature of the gas sample whose volume is fixed are related with
one or more of the following
( 1)\frac{p_{1}}{r_{1}}=\frac{p_{2}}{r_{2}} (b)
() \frac{p_{2}}{r_{1}}\approx\frac{p_{1}}{r_{2}} ) \frac{p_{1}}{T_{2}}=\frac{p_{2}}{r_{1}}
\frac{p_{1}}{T_{1}}=\frac{T_{2}}{p_{2}}
The correct equation relate pressure and absolute temperature when volume is fixed is:
(1) $\frac{p_{1}}{T_{1}}=\frac{p_{2}}{T_{2}}$
This equation is known as the Gay-Lussac's Law or the Pressure-Temperature Law. It states that the ratio of the initial pressure and temperature is equal to the ratio of the final pressure and temperature for a gas sample with fixed volume.
