Question

4. 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 gets reconverted into water ate 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 the energy released during the process S known as?

Answer 1

a) 100°C=373K
B)evaporation
C)latent heat of vaporisation
D)condensation

Answer 2

Answer:

A) 100°C = 373 K is the numerical value of x in kelvin.

B) Evaporation is process called R in the given statement. Evaporation is the process in which liquid is converted into gaseous state.

C) “Latent heat of vaporization” is the energy absorbed in the process of R.

D) Condensation is the process of S. Condensation is the process in which gas is converted into gas state.

E) Latent heat is the energy used in the process S.
