2012 MECHANICAL MOCK FOR SLIET LEET Thermodynamics Section 1 16. second law of thermodynamics defines 1. Enthalpy 2. Work 3.Heat 4. Entropy 17.The heat flows from a cold body to a hot body with the aid of an external source. This statement is given by 1. Kelvin 2.Joule 3. Clausius 4. Gay-Lussac 18. A process in which no heat is supplied and rejected is known as an adiabatic process. But if entropy is not constant, then this process is called 1. Isentropic process 2.Isothermal process 3. Hyperbolic process 4. Polytropic process 19. During reversible adiabatic expansion 1. Entropy remains constant 2.Temperature remains constant 3.Enthalpy remains constant constant 4. Internal energy remains constant 20. The entropy of an isolated increases during a 1.Reversible process 2. Isentropic process 3.Ideal process 4.Irreversible process Pages: 1 2 3 4 5 6 7 8 9 10 11 12 13 Pages ( 4 of 13 ): « Previous123 4 56 ... 13Next »
