Question

What are isochores? From the three isochores I, II, III given below, for a certain amount of ideal Gas,What is the correct arrangement of volumes V₁,V₂ and V₃.

Answer 1

Isochore is the plot between P and T for a definite amount of a gas at a constant volume. From different isochors at different volumes draw a line parallel to Temperature axis represent a constant P and cutting the three isochors at T₁,T₂ and T₃ respectively.Fr om the graph we find T₁,>T₂ >T₃. Since V α T, at constant P. Thus V₁ > V₂ > V₃.
