Question

we have a question in thermodynamics.

is the process from C-->A a adiabatical process? How do we calculate the heat and work of this process?

Answer 1

i cant see any image on that link.
do i have to sing up for that?

Answer 2

strange, i tried with several computers and it works for all.
you have to click "continue to media" then you see the picture/question...
i attached now

Answer 3

here line CA passes through the origin..so
\[(pressure)P \alpha V(volume)\]
or\[P=kV\] here k is proportionality const
or \[PV ^{-1}=k\]
for adiabatic it should have been
\[PV ^{\gamma}=k\],...so its not adiabatic process where\[\gamma=5/3\]
