A freezer sustains a cold environment of -24°C and exhausts its heat at 36°C. Assume a Carnot cycle. How much does it cost to remove 288 kJ of heat from the cold environment if the price of energy consumption is 13.5 cents per kWh? Express your answer in cents, to at least two places after the decimal point.

please answer it answer it in 1hr.

find the answer A piston-cylinder device provides 8 kJ of work to an external device. 2 kg of air contained inside the cylinder. If the internal energy of the air increases by 2 kJ/kg during the process, the heat transfer in kJ is Write the answer up to the nearest WHOLE NUMBER.

How many Btu/h would be produced in a 12-kW electricheater?

An electric resistance heater is used to provide space heating at an efficiency level of 100%. The electricity is sold at $0.13 per kWh. Question: How much money is needed if 1137.8 MBH is demanded? Hint: 1 MBH equals 1,000 btuh

Final answer in 4 decimal places.

At a given instant, a closed system is loosing 0.21 kW of heat to the outside atmosphere. A battery inside the system keeps it warm by powering a 40 W internal heating lamp. A shaft transfers 0.21 kW of work into the system at the same time. Part A Determine the rate of external work transfer, the rate of heat transfer, and dE/dt of the system. Express your answers, separated by commas, to two significant figures, if necessary. Vo AEO It vec ? Wert = Q kW, kW, kW
