Calculate the external work done when an ideal gas is expanded adiabatically.

Calculate the external work done when an ideal gas is expanded isothermally

For two mole of an ideal gas :

What is an ideal gas ?

Inversion temperature (T_(i)=(2a)/(Rb)) is defined as the temperature above which if gas is expanded adiabatically it gets warm up but if temperature of gas is lower than T_(i) then it will cool down. What will happen to gas if it is adiabatically expanded at 50^(@)C if its Boyle's temperature is 20^(@)C

Calculate the work done in isothermal reversible change.

Calculate the work done by the system in an irreversible (single step) adiabatic expansion of 2 mole of a polyatomic gas (gamma=4//3) from 300 K and pressure 10 atm to 1 atm :

An ideal gas with pressure P, volume V and temperature T is expanded isothermally to a volume 2V and a final pressure P_i , If the same gas is expanded adiabatically to a volume 2V and a final pressure P_alpha find the value of ratio P_alpha/P_i . The ratio of the specific heats for the gas is 1.67.
