Question

The first law of thermodynamics is a statement of conservation of energy. The temperature of a gas is a measure of the potential energy of its molecules. At constant volume, increasing the pressure of a gas increases its temperature. The entropy of a closed system can decrease. An engine can be constructed which will convert 100% of the available heat into work. The work done during a constant volume process is zero. It is impossible to transfer heat from a low temperature reservoir to a high temperature reservoir. All real world thermodynamic processes are irreversible. The processes in the Carnot cycle are reversible. Therefore the total entropy change for the Carnot cycle is zero.

Explanation / Answer

42 TRUE

43.FALSE, the average kinetic energy

44. TRUE, according to ideal gas law

45. TRUE, since S = Q/T; closed system does not means isolated system

46. FALSE; impossible to 2nd law

47. TRUE

48. FALSE, you can do that adding energy i.e. a Air conditioner

49. True

50- TRUE, even though this engine does not exist in ereality
