Question
Explain, why it is not possible to increase the temperature of a gas while keeping its volume and pressure constant?
✓
Answer
According to kinetic theory of gases,$\text{P}=\frac{1}{3}\rho\text{C}^2=\frac{1}{3}\frac{\text{M}}{\text{V}}\text{C}^2=\frac{1}{3}\frac{\text{M}}{\text{V}}\text{KT}$ ($\because C^2$ = KT. when K is constanst)
$\therefore\text{T}\propto\text{PV}$
Now as T is directly proportional to the product of P and V. If P and V are constant, then T is also constant.
