- A carnot enine removes 1200J of heat from a high temperature source and dumps 450J to the atmosphere at18.0C What is the efficiency of the engine?What is the temperature of thehot reservoir?1 kg of air is reversibly heated at constant pressure from an initial state of 300 K and 1 bar until its volume increases to three times its initial value. Determine the internal energy changes, entapy, and heat and work requirements for this process. The molar mass of air is 28.9 g / mol. Write down all your assumptions made. w= dU= dH= Q=A heat engine operates under the following conditions: heat exchanged via exhaust Qc = -2500 J, work done W = -1000 J. What is the efficiency of the engine? %3D
- What is the net work Wnet,s = ΣWs done by the gas in this process and What is the heat QH taken from the hot reservoir? Please answer both, its my last question remaining!Explain 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 heat engine using 0.03 moles of helium follows the cycle shown in the diagram. What is the volume Vmax in m3?
