The first law of thermodynamics was given as q=DeltaU+(-w) , where q is heat given to a system and DeltaU represents increase in internal energy and -w is work done by the system. Various processes such as isothermal, adiabatic, cyclic, isobaric and isochoric process in terms of I law of thermodynamics leads for important results. The molar heat capacity for 1 mole of monoatomic gas is 3/2 R at constant volume and 5/2 R at constant pressure. 1 mole of a monoatomic gas is expanded through path ABC as shown in figure: select the correct statements:
