An ideal gas is allowed to expand both reversibly and irreversibly in an isolated system. If Ti is the initial temperature and Tf is the final temperature, which of the following statement is correct:
  • a)
    (Tf)irrev > (Tf)rev
  • b)
    T> Ti for reversible process but Tf = Ti for irreversible process
  • c)
    (Tf)irrev = (Tf)rev
  • d)
    Tf = Ti for both reversible and irreversible processes
Correct answer is option 'A'. Can you explain this answer?

An ideal gas is allowed to expand both reversibly and irreversibly in ...
(Tf)rev

b) (Tf)irrev < />

c) (Tf)irrev > (Tf)rev

d) (Tf)irrev = (Tf)rev

The correct answer is a) (Tf)irrev = (Tf)rev. The temperature change of an ideal gas during expansion is determined by the change in internal energy of the gas. In an isolated system, the total internal energy of the system is conserved. Therefore, the change in internal energy of the gas is the same for both reversible and irreversible expansions. This means that the final temperature of the gas is the same for both types of expansions.
