A fixed mass $$'m'$$ of a gas is subjected to transformation
of states from $$K$$ to $$L$$ to $$M$$ to $$N$$ and back to $$K$$ as shown in the figure :
A fixed mass $$'m'$$ of a gas is subjected to transformation
of states from $$K$$ to $$L$$ to $$M$$ to $$N$$ and back to $$K$$ as shown in the figure :
The succeeding operations that enable this transformation of states are
A.
heating, cooling, heating, cooling
B.
cooling, heating, cooling, heating
C.
heating, cooling, cooling, heating
D.
cooling, heating, heating, cooling
Answer :
heating, cooling, cooling, heating
Solution :
$$\eqalign{ & K \to L;\,{\text{heating, isobaric}} \cr & L \to M;\,{\text{cooling, isochoric}} \cr & M \to N,\,{\text{cooling, isobaric}} \cr & N \to K;{\text{heating, isochoric}} \cr} $$
$$\eqalign{ & K \to L;\,{\text{heating, isobaric}} \cr & L \to M;\,{\text{cooling, isochoric}} \cr & M \to N,\,{\text{cooling, isobaric}} \cr & N \to K;{\text{heating, isochoric}} \cr} $$
