The triple point of a pure substance is that point on a temp

The triple point of a pure substance is that point on a temperature-entropy diagram where the saturated liquid and saturated vapor states arc identical, i.e. h_g = 0: TRUE [] or FALSE [] The critical point of a substance is completely defined by_____intensive, independent properties. The First Law of Thermodynamics deals with the conservation of entropy. TRUE [] or FALSE [] The work done in a constant-pressure process from state 1 to state 2 can be calculated as vDeltap. TRUE [] or FALSE [] The heat transfer in an isentroplc process is_____. In general, the perfect gas law can be used for most gases for_____temperatures and_____pressures. State the Third Law of Thermodynamics. For a perfect gas with constant specific heat the change in internal energy from one state to another is calculated as Deltau =_____. For real gases, a compressibility factor may be used, which is more accurate than the property tables for that particular gas. TRUE [] or FALSE [] Name one factor which makes processes irreversible:_____

Solution

1.true

2.thermodynamic end point of phase

3.false. only second law deals with entropy.

4.fals. in constent pressure processes change in pressure is zero b/s wrok done zero

5.zero,  During a reversible process the quantity of heat transferred is directly proportional to the system\'s entropy change

6.high temperatures and low pressures

7.The third law of thermodynamics is sometimes stated as follows, regarding the properties of systems in equilibrium at absolute zero temperature

8.U=mC_v(T₁-T₂)

9.fals

10.Friction, Free Expansion, Mixing of fluids, Heat transfer through a finite temperature difference
