In an isothermal and irreversible expansion of a gas, what is the relationship between q and w?

Options

  1. Aq = w
  2. Bq < w
  3. Cq > w
  4. Dq is unrelated to w.

Correct answer

A. q = w

Step-by-step solution

In an isothermal expansion, both q (heat absorbed) and w (work done) are equal and have the same magnitude but opposite signs.
