Chemical Engineering Thermodynamics - Section 1 (4)

"At the absolute zero temperature, the entropy of every perfectly crystalline substance becomes zero". This follows from the

The freezing point of a liquid decreases when the pressure is increased, if the liquid __________ while freezing.

If the vapour pressure at two temperatures of a solid phase in equilibrium with its liquid phase are known, then the latent heat of fusion can be calculated by the

No work is done by the system, when a reaction occurs at constant

Isobaric process means a constant process.

Entropy of an ideal gas depends upon its

Keeping the pressure constant, to double the volume of a given mass of an ideal gas at 27°C, the temperature should be raised to __________ °C.

The theoretical minimum work required to separate one mole of a liquid mixture at 1 atm, containing 50 mole % each of n- heptane and n- octane into pure compounds each at 1 atm is
