The figure shows the temperature of water as a function of time as it is being heated. There are 2 intervals when the temperature doesn’t change. This is because: A. The pressure remains constant B. The heat is transformed into work C. The entropy remains constant D. The phase is changing E. The thermal energy remains constant
Steam engines have boilers operating at 500K. The energy from a burning fuel converts water into steam and this steam then moves the piston. the temperature of the cold reservoir from the outside air is around 300K and the efficiency of both engines is 40%. to be able to increase the efficiency of the two machines again by increasing Th or by reducing Tc. Identify what factors cause an increase in engine efficiency in both engines and which are more effective in increasing engine efficiency?
