the system along
these two paths are Q1, Q2 and W1, W2
respectively, then​

Answer 1

Answer:

i hope it was helpful:)

Explanation:

A system is taken from state A to state B along 2 different paths 1 and 2 . The heat absorbed and work done by the system along these 2 paths are Q

1

,Q

2

and W

1

,W

2

By first law of thermodynamics

Q

1

+(−W

1

)=Q

2

+(−W

2

)

Hence Q

1

−W

1

=Q

2

−W

2

is correct.
