Question

(a)
An impure sample of Ammonium chloride is given to
you how can you obtain pure sample of ammonium
chloride from it ? Describe it.
(b)How does degree celsious (°C) related to Kelvin(K)?
Write boiling point and melting point temperature of
water in °C and convert them into "K".
​

Answer 1

Explanation:

(a) we can obtain pure sample of Ammonium Chloride by the process of sublimation

(b) K= C +273K

(c) boiling point of water is 100 degree C and melting point of water is 0 degree C in Kelvin it is

100 degree C = 373k and 0 degree = 273k
