For the process

$H_{2} O (l) (1 b a r, 373 K) \to H_{2} O (g) (1 b a r, 373 K)$ , the correct set of thermodynamic parameters is

Options:

Answer:

Solution:

The change given is occurring at the boiling point of the liquid, where, at a given pressure and temperature the liquid-vapour system virtually remains at equilibrium and hence $∆ G = 0$ . Also due to absorption of heat as latent heat of vaporization, or due to change from liquid to gaseous state where randomness has also increased, $∆ S > 0$ .

Hence (A) is correct option
