THERMODYNAMICS Internal energy : (U) U = PE + KE of molecules. Where KE of molecule = f KT (f = stratum of freedom & K is Boltzmann aeonian) and PE of 2 molecules depends upon intermolecular distance (ro). ordinal integrity of thermodynamic : If the bodies be in thermal equilibrium with a third body separately, thus those two bodies are in thermally in equilibrium with each other. scratch line constabulary of Thermodynamics : The amount of waken supplied to a organization (dQ) qualified of doing outer work is equal to sum of increase in the inwrought energy (dU) and external work through with(p) by system (dW) dQ = dU + dW. dQ = +ve when warmth supplied = - ve when heat rejected dU = +ve when temperature increases = ve when temperature decreases dW = +ve when work is done by system. = ve when work is done on system. Specific heats of driftes : occur of inflame required to raise the temperature of whole system by 1°C is Heat capacity of a shooter (C) C Cv Cv Cp Cp dQ ndT molar specific heat of turgidness at constant volume. specific heat of a gas as constant volume. molar specific heat of gas as constant pressure. specific heat of gas at constant pressure units of Cp and Cv are J/mole/k units of Cp and Cv are J/kg/k Cp > Cv Relation betwen Specificheats of the gas a) Cp Cv = r = b) Cp- CV = R R - universal gas constant.

It follows Boyles law. P1V1 = P2V2. During isothermal change, internal energy remains constant. U is constant du = 0 dQ = dW = pdV Ex.
