Question

What is the relation between P and V in isothermal process ?​

Answer 1

Answer:

The name of this law is the Boyle's law; mathematical formula is.p1V1 = p2V. When the process is ideal than the temperature of the gas is still constant.

Answer 2

As we know

$\sf \: by \:Boyle's\: law, \\ \sf \: PV=constant$

at constant temperature (isothermal process)

however, that’s true only at low pressures and high temperatures (when we can treat gases as ideal gases).

So we could use van der Waals equation

$\sf \: [p+a( \frac{ n}{V})2]( \frac{V}{n}−b)=RT=constant$
