At critical temperature, the surface tension of liquid is (a) zero (b) infinity (c) unity (d) same as that at any other temperature

Answer: (a). At the critical temperature the liquid and vapour become identical, so there is no free surface. With no surface, there is no surface tension. So the answer is (a) zero.
