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:
The answer is "+9.05 kw"
Explanation:
In the given question some information is missing which can be given in the following attachment.
The solution to this question can be defined as follows:
let assume that flow is from 1 to 2 then
Q= 1kw
m=0.1 kg/s
From the steady flow energy equation is:
If the sign of the work performed is positive, it means the work is done on the surrounding so, that the expected direction of the flow is right.
