Question

A graph is plotted with (PV) on y-axis and V on x-axis where P and V denote the
pressure and volume of a fixed mass of gas respectively. At constant temperature,
the graph is a
(1) Straight line passing through origin
(2) Straight line parallel to the x-axis
(3) Rectangular hyperbola
(4) Parabola​

Answer 1

Answer:

T

PV

= nR = (

M

m

)R

Or,

T

PV

=(

M

R

)m

i.e.,

T

PV

versus on graph is straight line passing through origin with slope R/M. i.e., the slope depends on molecular mass of the gas M and is different for different gases
