11. A heat engine operates between two reservoirs at 800 and 20°C. One-half of the work output of the heat engine is used to drive a Carnot heat pump that removes heat from the cold surroundings at 2°C and transfers it to a house maintained at 22°C.

Identify one of the errors in the bar chart. Each bar's length should be taller and the width wider. The lengths and widths of the bars are proportional. The lengths and widths of the bars are not proportional.

A well-established way of power generation involves the utilization of geothermal energy-the energy of hot water that exists naturally underground - as the heat source.

Students are expected to respond to one of the two questions described below. Students should provide examples to clarify their response. 1.

Water circulates throughout a house in a hot water heating system. If the water is pumped at a speed of 0.50m/s through a 4.0-cm diameter pipe in the basement under a pressure of 3.03x10^5 Pa, what will be the velocity and pressure in a 2.

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.
