Question

at constant volume what is the value of pressure coefficient of a gas...
plz answer this...​

Answer 1

Answer:

Pressure coefficient of a gas (β): At constant volume the ratio of increase of pressure per 1°C rise in temperature to its original pressure at 0°C is called pressure coefficient of gas.

Answer 2

The value of pressure cofficient of a gas at constant volume is th ratio of difference of final pressure and initial pressure to it's initial pressure.

Explanation:

Consider a gas at initial temprature '$T_{1}$' whose pressure at that temprature is '$P_{1}$'.

Volume is taken constant in whole process. (given in equation)

Now, consider the same gas at final temprature '$T_{2}$', where it's pressure is '$P_{2}$'.

Hence, it's pressure cofficient is

        ⇒ $\alpha_{p} = \frac{P_{2} - P_{1} }{P_{1}}$

'$\alpha _{p}$' is the denotion of pressure cofficient.
