A cyclic process ABCD is shown in the p-V diagram. Which of the following curves represents the same process if BC and DA are isothermal processes?
Options:(select one or more)
Answer:
A, B
Solution:
AB is isobaric: V and T both increase. BC is isothermal expansion: V increases, p decreases.
CD is isochoric: p and T both decrease. DA is isothermal compression: V decreases, p increases.
Only curves (A) and (B) show all four features consistently - options (A) and (B).
