Which
of the statement is TRUE?
इनमें से कौन सा कथन सत्य है?
Two
reversible adiabatic paths intersect at a point
Two reversible
adiabatic can never intersect each other.
Two
property line can never intersect each other.
Both
two reversible adiabatic can never intersect each other and two property line
can never intersect each other.
Two reversible
adiabatic can never intersect each other.
As per Kelvin-Planck’s statement heat
loss 
always.
(Figure: Graph plotted to understand
this impossible case)
We can clearly see in the p-V diagram
that only heat addition are there but heat rejection is not possible due to
intersection of two reversible adiabatic curves which violates Kelvin-Planck’s
statement.
Hence, the correct option is (B).
