57. mmh A Carnot engine operates between temperatures of 650 and350 K. To improve the efficiency of the engine, it is decided either toraise the temperature of the hot reservoir by 40 K or to lower the temper-ature of the cold reservoir by 40 K. Which change gives the greater im-provement? Justify your answer by calculating the efficiency in each case.

Given: The temperature of the hot reservoir is 650 K. The temperature of the cold reservoir is 350…

5:59 PM Thu Apr 29 L 40% O Submit Problem 2 Unanswered An engine runs with an intake temperature of TH = 450K and exhaust temperature of Tc = 300K. The engine's manufacturer claims the engine has an efficiency of 30%. Which of the following statements is correct?- The claimed efficiency is bogus because it violates the 2nd law of A thermodynamics. The claimed efficiency does not violate the 2nd law of thermodynamics. Submit
The first law of thermodynamics is generally thought to be the least demanding to grasp, as it is an extension of the law of conservation of energy, meaning that energy can be neither created nor destroyed. (a) The variations of properties during phase change processes are best studied and understood with the help of property diagrams. Point out schematically the difference between the P-v diagram in respective of: 1. contracts on freezing. ii. expands on freezing.
