Question

When water is heated to a temperature X, it gets converted into steam at temperature X by a process called R. And when steam at temperature X is cooled, it reconverted into the water at the same temperature X by a process called S.

(a) How much is the value of X in Kelvin?

(b) What is the process R called?

(c) What is the name of the energy absorbed during the process R?

(d) What is process S known as?

(e) What is the name of energy released during the process S known as?

Answer 1

(a) 373 Kelvin

The boiling point of water is ${100}^{\circ }$C, that is 100 + 273 = 373K

(b) Vaporisation

(c) Latent heat of Vaporisation

(d) Condensation

(e) Latent heat of condensation (negative value of vaporization)
