- 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. SubmitExplain why it is impossivle for any process to be more than 100% efficient. Give an example of a process that is not very effecient and explain where it 'loses' energy.A thermodynamic process can be represented using a PV diagram where the pressure and volume at every stage is recorded. In the thermodynamic process shown below the work done by the system is РА A O the area under the PV curve and positive the area under the PV curve and negative B is the product of the change in volume during the process and the change in pressure. cannot be found from the PV graph
