5 lb of propane is contained in a closed, rigid tank initially at 80 lbf/in^2, 110 degrees Fahrenheit. Heat transfer occurs unti
l the final temperature in the tank is 0 degrees Fahrenheit. Kinetic and potential energy effects are negligible. Show the initial and final states on a T-v diagram and determine the amount of energy transfer by heat, in Btu.

Answer: c) 450 kPa
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
where,
= initial pressure of gas = 150 kPa
= final pressure of gas = ?
= initial volume of gas = v L
= final volume of gas =
Therefore, the new pressure of the gas will be 450 kPa.
