A thermodynamic system undergoes a process where its internal energy increases by 200 J. During this time interval, 75J of heat is transferred from the system. How much energy in the form of work is transferred?

An air-filled cylinder with a movable piston has a heat reservoir in contact with it. The heat reservoir transfers 850 ) of energy into the cylinder. Due to the energy transfer, the piston does 437 J of work on the environment. What is the change in internal energy of the system? A 1.9J 413 J 1287 J D 371 000 J

please answer the following   As a gasoline engine is running, an amount of gasoline containing 12,000 J of chemical potential energy is burned in 1 s. During that second, the engine does 4,000 J of work.   What is the engine's efficiency (in percent)?     The burning gasoline has a temperature of about 4,300°F (2,600 K). The waste heat from the engine flows into air at about 88°F (304 K). What is the Carnot efficiency (in percent) of a heat engine operating between these two temperatures?

A heat engine takes in 2500J and does 1500J of work.   a) How much energy is expelled as waste?            b) What is the efficiency of the engine?

The engine of a large ship does 1.97  1010 J of work with an efficiency of 8.60%. (a) How much waste heat is produced? (b) How many barrels of fuel are consumed if each barrel produces 6.00  109 J of heat when burned?

As a gasoline engine is running, an amount of gasoline containing 18,500 J of chemical potential energy is burned in 1 s. During that second, the engine does 3,700 J of work. (a) What is the engine's efficiency (in percent)?  % (b) The burning gasoline has a temperature of about 4,100°F (2,500 K). The waste heat from the engine flows into air at about 90°F (305 K). What is the Carnot efficiency (in percent) of a heat engine operating between these two temperatures?  %

During each cycle of operation, a refrigerator absorbs 230 J of heat from the freezer and expels 356 J of heat to the room. How much work input is required in each cycle? 310 J 460 J O 126 J 712 J O 586 J

A graduate student leaves a cylinder of carbon dioxide sitting in the sun. The cylinder absorbs 25.2 J of energy while sitting in the sun. A piston in the cylinder moves upward. The carbon dioxide did 12 J of work on the piston to move it upward. Find the change in internal energy of the carbon dioxide.

An engine releases 0.150 kJ of heat for every 0.310 kJ of work it does. What is the efficiency of the engine?
