what will a graph of volume against temperate, it's gradient give? pressure??

Answer 1

For an ideal gas, P*V=n*R*T (r = constant). Therefore a graph of volume vs temp is given by

V=n*R*T/P.

The slope (gradient) of this is n*R/P, a constant times the inverse of pressure.

R is the universal gas constant, n = no of moles of gas in the volume
