Question

When water is cooled to a temperature X,it gets converted into ice at temperature X by a process called P and when ice at temperature X is warmed, it gets reconverted into water at the same temperature X in a process called Q.
(i) State the value of temperature X in Kelvin?
(ii)Describe the process P and Q? (iii) Indicate and elaborate:
(a) Energy released during process P.
(b) Energy absorbed during process Q.

Answer 1

Answer:

Explanation:

i) Water gets converted into ice at freezing point which is 0°C which when converted into Kelvin scale is 273k. [x=273K]

ii) The process is called as freezing.

Energy released and absorbed during P and Q is called latent heat of vapourization.
