31. The energy and the-momentum are " separately conserved " quantities for isolated systems in the Lagrangian framework. 32. Likoma District has two separate isolated systems with a total installed thermal power plants capacity of 1.050MW. 33. The planets " are not isolated systems ," 34. The entropy of an isolated system in thermal equilibrium containing an amount of energy of E is: 35. Now, by microstate of an isolated system ( its information-theoretic joint entropy ) is constant in time. 36. The fundamental definition of entropy of an isolated system containing an amount of energy of E is: 37. This problem illustrates some of the difficulties one faces when talking about the mass of non-isolated systems . 38. Isolated systems are a special case of adiabatic systems, so this statement is also valid for isolated systems . 39. For isolated systems , entropy never decreases. 40. Isolated systems are a special case of adiabatic systems, so this statement is also valid for isolated systems.
