Question

State whether true or false :
The isothermal elasticity of the gas is equal to its final pressure.

• A. True
• B. False

Answer 1

The correct option is A True

Isothermal electricity $=\frac{1}{\frac{-1}{v}{\left(\frac{\partial V}{\partial P}\right)}_T}$

Applying : $PV=nRT$

for isothermal $PV=$ Const.

$\Rightarrow PdV+VdP=0$

$\Rightarrow \frac{dV}{dP}=-\frac{V}{P}$

$\Rightarrow$ Isothermal Elasticity $=-V\frac{dP}{dV}$

$=-V\times \frac{-P}{V}$

$=P$ ( Pressure )

Hence, the answer is $P.$
