The work from a Carnot engine between two reservoirs at TH=847 K and T=523 K is used to operate a Carnot heat pump that removes heat from a reservoir at temperature T while discharging heat to another reservoir at temperature T. If the heat removed from the hot reservoir by the engine is the same amount by the heat pump from its cold reservoir, what is T? 323 X K.

A gas is compressed inside a cylinder with an average force of 40 N acts to move the piston 0.20 m. If no heat has time to move into or out of the gas, what is the change in internal energy of the gas?

The motor that drives a refrigerator produces 151 W of useful power. The hot and cold temperatures of the heat reservoirs are 20.0°C and -5.00°C. What is the maximum possible amount of ice it can produce in 2.00 h from water that is initially at 8.00°C? Latent heat of fusion of ice is 333700 J/kg and specific heat capacity of water is 4186 J/(kg-K). kg

Problem 1: Which of the following would violate the Second Law of Thermodynamics? Choose one that applies. OA 130 °F cup of hot coffee is placed on the table in a 75 °F room. Without any work being exerted and with no chemical reactions the cup of coffee heats up. O1,000 kJ of energy are available from a hot thermal reservoir. A heat engine converts 600 kJ to work and rejects 500 kJ to a lower temperature reservoir. A swinging pendulum gets lower and lower as friction takes energy out of the system. As a block slides down a rough incline heat is generated from friction. O Work is done and heat is made to go from a lower temperature reservoir to a higher temperature reservoir. O An inventor builds a device that is able to convert a specific amount of heat entirely to work in a thermodynamic cycle.
