JUST ANSWER TRUE OR FALSE
JUST ANSWER TRUE OR FALSE
Theory (1 points each) 1. The Clapeyron equation is an exact equation and applies to the phase equilibrium of any two phases of a pure species. 2. The Clausius-Clapeyron equation is an exact equation that applies to VLE and SVE only. 3. Interpolation is often needed when using tabulated thermodynamic properties. 4. When a fluid flows through a restriction without any appreciable change in kinetic or potential energy, the primary result of the process is a reduction of the fluid pressure. 5. The minimum isentropic shaft work Ws obtained from a turbine, given the inlet conditions and discharge pressure, occurs when the turbine is adiabatic. 6. Compression processes bring pressure increases. 7. When the liquid form of a pure substance solidifies, there is no change in its temperature, and requires the transfer of finite amounts of heat. 8. The process described in the previous question is an example of the so-called latent heat of sublimation and it is 9. The internal-combustion engine is an example of a heat engine. 10. Ineffective engines will have a W<0. 11. A Carnot engine operates reversibly in all respects. If its temperature levels are TH (hot) and TC (cold), its efficiency approaches unity only when Tc approaches infinity. 12. Entropy is not conserved. +
