answer is straight line parallel to y axis when pressure is taken on y axis and temperature is taken on x axis.

please tell me the way to fiqure it out.

Answer 1

The P-V graph given above is for isothermal process
$p(v) = \frac{nrt}{v}$
There is a constant temperature T all through the process hence

For P-T graph
Temperature is constant
as per gas law
PV=nRT
PV= constant
$t = \frac{pv}{nr}$

PV is constant
r is universal constant
and n is no of moles
hence T is always constant
