(b) Ice, water and water vapour look different and display different ——
properties but they are ——— the same.
(c) A mixture of chloroform and water taken in a separating funnel is mixed
and left undisturbed for some time. The upper layer in the separating
funnel will be of——— and the lower layer will be that of ———.
(d) A mixture of two or more miscible liquids, for which the difference in
the boiling points is less than 25 K can be separated by the process
called———.

Answer 1

Answer:

(a) A colloid is a heterogeneous mixture and its components can be separated by the technique known as centrifugation.

(b) Ice, water and water vapour look different and display different physical properties but they are chemically the same.

(c) A mixture of chloroform and water taken in a separating funnel is mixed and left undisturbed for some time. The upper layer in the separating funnel will be of water and the lower layer will be that of chloroform.

(d) A mixture of two or more miscible liquids, for which the difference in the boiling points is less than 25 K can be separated by the process called fractional distillation.
