The ideal gas law relates the pressure P, volume V, absolute temperature T, and amount of gas n. The law is P = nRT/V 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 atm. In December when the temperature is 4 degrees Farenheight (-15 C), the volume of gas in the tank is 28,500 ft^3. What will the volume of the same quantity of gas be in July when the temperature is 88 F (31 C)? (Hint: Use the fact that n, R, and P are constant in the problem. Note also that K = C + 273.2
