The pressure of gas at 0°c is 50 cm of Hg at constant volume heated to 80°c then pressure is 64cm of Hg the pressure coefficient of gas...
pressure coefficient of gas is given by,
where, is pressure of gas at temperature T and is pressure of gas at temperature 0°C.
here, = 64cm Hg
= 50cm Hg
T = 80°C
then, α = (64 - 50)/(50 × 80)
= 14/4000
= 0.0035 /°C
hence, pressure coefficient of gas is 0.0035/°C
