- Name the process associated with the following:-
Dry ice is kept at room temp. and under one at. Pressure.
A drop of ink placed on the surface of water is put in a glass spreads throughout water.
Milk is churned to separate cream from it.
Settling of sand when a mixture of sand and water is left undisturbed for sometime.
A crystals of potassium permagnate is put in water contained in a beaker and stirred with a glass
rod.
Answers
a]. Sublimation:
When dry ice is kept open at room temperature, it turns into gas.
b] Diffusion:
When drop of ink is placed on the surface of water it spreads over the water and mixes.
c]. Diffusion
KMnO4 Crystals mixes with the particles of the water.
d].Vapourization:
Since acetone vaporizes at room temperature , it is always stored in bottle.
e].Centrifugation:
Milk is churned to separate from curd by the centrifugation process where the lighter particles will float and denser particles will settle at bottom in centrifuge machine.
f]. Sedimentation:
Sedimentation is process where sand will settle at bottom of water if left undisturbed.
g]. Dissolution:
This involves a solid going into a liquid phase, but dissolution can involve other transformations as well. For example, when alloys form, one solid dissolves into another to form a solid solution.
