Question

During the thermodynamic process shown in figure for an ideal gas
A) Del t=0
B) Del q=0
C) w<0
D) Del U >0

Answer 1

Answer:

First law of thermodynamics states ΔU=Q−W.

since ΔU=0 therefore W=Q

W=PV

PV=Q

P=

V

Q

since P is inversely propositional to the value of V hence graph is hyperbola.

Option B represents the graph best
