P / T = nr/ v. T/P=V/nr
v / T = n R / P. T / V= P/nR
P /v= -nRT / v² v/P= -nRT/p²
Thermodynamic coefficient
Alpha =
isobaric thermal expansion coefficient
relative change in volume with respect to change in temperature at constant P
Alpha = [dv÷v / dT ] p = 1/v [dv / dT ] p
Unit of alpha
K-¹ per kelvin
For a ideal gas value of alpha
Alpha = nR/PV = nR/ nRT = 1/T
Beta equals to
Isothermal compressibility factor
The relative negative change in volume with respect to change in pressure at constant temperature
Unit of beta
Per atm
For ideal gas beta =
1/p
Gamma =
Isochroic temperature based pressure change
The relative change in pressure with respectvto change in temperature at constant volume
Unit of gamma is
Per kelvin
For ideal gas gamma = 1/T
