Question

An ideal gas is taken through a process as
shown in the figure. It absorbs 100 J of energy
during the process AB. No heat is absorbed
or rejected along the process BC and rejectes
140 J during the process CA. During the
process BC, 60 J of work is done on the gas.
Internal energy of the gas at A is 2000 J. The
internal energy at C is
1) 1620 J
2) 620 J
3) 216 J
4) 2160 J​

Answer 1

Answer:

the internal energy at C is 1620 J

Answer 2

option 4) is right 2160J answer
