What is the entropy change (in J/K) of 71 g of steam at 100°C when it condenses to water at the same temperature?

Answer : The change in entropy is

Explanation :

Formula used :

where,

= change in entropy = ?

m = mass of water = 71 g

= heat of vaporization of water =

T = temperature =

Now put all the given values in the above formula, we get:

Therefore, the change in entropy is

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
