A system goes...

Question

A system goes from A to B by two different paths in the P-V diagram as shown in figure. Heat given to the system in path 1 is 1100 J, the work done by the system along path 1 is more than path 2 by 150 J. The heat exchanged by the system in path 2 is :

Solution

The correct option is D 950 J
Work done $=$ Area under P-V graph.
From graph
$1100 = 150 + W_{2} W_{2} = 950 J$
