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). kgProblem 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.
