Please help! please show the formulas used so I can try to understand this or explain the concepts Thank You!
When a gas follows path 123 on the PV diagram in the figure below, 407 J of heat flows into the system and 161 J of work is done.
a) what is the change in the internal energy?
b) How much heat flows into the system if the process follows path 143
For this and the following part, represent net work done BY the system as a positive number and net work don ON the system as a negative number
c) What net work would be done on or by the system if the system followed path 12341?
d) What net work would be done on or by the system if the system follow path 14321?
e) What is the change in internal elergy of the system in the processes described in parts c and d?
Explanation / Answer
a) change in internal energy = Q + W
= 407 - 161 = 246 J
b) heat flows into the system if the process follows path 143 = 407 J
c) net work would be done = 0 J
d) net work would be done = 0 J
e) change in internal elergy of the system = 407 J
