Question

The_____of pressure and volume of an enclosed gas at a given temperature is always a constant quantity.

Answer 1

According to the Boyle's law-

At constant temperature, the product of the pressure and volume of a given mass of an ideal gas in a closed system is always constant. It can be verified experimentally using a pressure gauge and a variable volume container.

T=constant

$\mathrm{P}\mathrm{is}\mathrm{directly}\mathrm{propotional}\mathrm{to}\frac{1}{\mathrm{V}}$

$\mathrm{PV}=\mathrm{K}$

K=constant.

This is why the product of pressure and volume is always a constant quantity.
