An ideal gas is allowed to expand both reversibly and irreversibly in an isolated system. If T_i is the initial temperature and T_f is the final temperature, which of the following statements is correct?

Options

  1. A(T_f )_ irev > (T_f )_ rev
  2. BT_f>T_i for reversible process but T_f=T_i for irreversible process
  3. C(T_ f )_ rev = (T_ f ) irrev
  4. DT_f=T_i for both reversible and irreversible processes

Correct answer

A. (T_f )_ irev > (T_f )_ rev
