Question

when water is converted into steam the enthalpy (a) increases (b) decreases (c) remains the same (d) is minimum 66.

Answer 1

increase s is the correct answer I think

Answer 2

Answer ⇒ Option (a). Increases.

Explanation ⇒ When water is converted into steam a energy is used, This means it is the Endothermic Process.

Now, In Endothermic Process, Energy is given a negative symbol. Thus, we say it is less.

Now,  Enthalpy will always have the opposite symbol than the Energy.

∴ Enthaly will be Positive. It means it is Increasing.

Hence, Option (a). is correct.
