Plz tell what is finite and intermediate expansion..... erature of the g as remains const

Refer to Ean. (1 dU=0 Further for an id Further Ior an ideal gas, Uis a function of tcmperature and as dU=0, tis mcans that temperature of the gas remains constant after expansion, i.e., dT= 0 cmperature and as dU= 0, this mcans that temperature of the dH=d (U+ P) = dU+ d (P) = dU+ d (RT) = dU+ RdT= 0+0=0 For-a finite change, the expressions for w, AUand AlH will be W-0, AU 0, AT=0, AH=0 .20) These expressions are sanme as for isothermal free expansion. Hence, we conclude that for free expansion, othermal and adiabatic expansions are identical. 35 IERMODYNAMICSI
