A.
Clausius-Clapeyron equation relates the latent heat of vaporisation to the slope of the vapor pressure curve |
|
B.
At the boiling point of liquid at the prevailing total pressure, saturated absolute humidity is infinite |
|
C.
Percentage saturation and relative saturation are numerically equal for an unsaturated vapor gas mixture |
|
D.
Clapeyron equation is given by,dP/dT = λ/T(VG - VL); where, P = vapor pressure, T = absolute temperature, λ = latent heat of vaporisation, VG and VL = vol |
