Enthalpy of Vaporizations: During evaporation of liquid, some absorption of heat from surroundings takes place. Hence, Liquid evaporation is fulfilled by increase in enthalpy. The increase in enthalpy while evaporation…
Relation between CP and CV in gaseous systems No external work is being done when a gas is heated at constant volume i.e. gas uses all the haet which is…
(a) We know that for one mole of an ideal gas, CV = (∂U/∂T) V Therefore, dU = CV dT For a finite change, ∆U = CV ∆T As for…
Temperature T = 37oC = 37 + 273 = 310 K Since the process is Isothermal, Therefore, ∆U=0 and ∆H = 0 (as for an isothermal expansion of an ideal…
We can calculate the change in change in thermodynamic properties like q , w , ∆U , ∆H with the help of first law of thermodynamics. The expansion can be…
As we know that if the quantity of heat transferred from the surrounding to the system is q and work done in the process is w, then the change in…
The absorption of heat by the system tends to raise the energy of the system. The performance of work by the system, on the other hand, tends to lower the…
Let us suppose that for an ideal gas, isothermal and adiabatic expansions have initial volume Vi and pressure be Pi to a common final volume Vf. If Piso and Padia…
The absorption of heat by the system tends to raise the energy of the system. The performance of work by the system, on the other hand, tends to lower the…
The required equation is 2C + H2 ———-> C2H5 Standard heat of formation i.e. ΔH =? Writing the thermo-chemical equation of the given data (i) C2 H2 + 5/2 O2…
