A hot water leak in one of the faucets of your apartment can be very wasteful. A continuous leak of one quart per hour (a "slow" leak) at 155 degrees°F causes a loss of 1.81 million Btu per year. Suppose your water is heated with electricity. a. How many pounds of coal delivered to your electric utility does this leak equate to if one pound of coal contains 12,000 Btu and the boiler combustion process and water distribution system have an overall efficiency of 28%? b. If a pound of coal produces 1.81 pounds of CO2 during the combustion process, how much extra carbon dioxide does the leaky faucet produce in a year

Krypton in a closed system is compressed adiabatically from 74 K and 1 bar to a final pressure of 24 bar. What is the final temperature in K? Assume krypton is an ideal gas. From Appendix B in the text, we can assume the heat capacity of krypton is independent of temperature and CP=2.5R , where R is the molar gas constant R=8.314 J/(mol K). For an ideal gas, recall CV=CP−R=1.5R. Report your answer in units of K using three decimal places.

Hello, I need help with the following (statistical) Thermodynamics problem. Thank you!
The ideal gas law relates the pressure P, volume V, absolute temperature T (Kelvin), and amount of gas n. The law is P = mAT where R is the gas constant. An engineer must design a large natural gas storage tank to be expandable to maintain the pressure constant at 2.2 atmospheres. In December when the temperature is -15°C, the volume of gas in the tank is 28,500 ft°. What will the volume of the same quantity of gas be in July when the temperature is 31°C? (Hint: Use the fact that n, R, and P are constant in this problem. Note also that Kelvin = °C+273.2)
