Because the segment of graph with the highest work is the hypotenuse (max area subtended with x axis)

I calculated work done by using area under pv graph

I know

Work done for cyclic process = area enclosed

I'm giving the reasoning for sign

PercyOP•1/22/25, 12:01 PM

ohhh okay

Nimboi•1/22/25, 12:02 PM

positive only

Nimboi•1/22/25, 12:02 PM

actually wait

Nimboi•1/22/25, 12:02 PM

does that differ from physics to chem?

idk

istg thermo is weird like that

ikr

@Percy okay so in physics clockwise = +ve, anticlock = -ve
and in chemistry work done has opposite signs compared to physics
so in chemistry work done clockwise is indeed negative
