Column - I	Column - II
a) Depression of freezing point	p) Plasmolysis
b) Elevation of boiling point	q) Use of salt in the boiling of eggs
c) Osmosis	r) Use of glycol in car radiators
d) Reverse osmosis	s) Preparation of drinking water from sea water

• A. A-R, B-Q, C-P, D-S
• B. A-P, B-Q, C-R, D-S
• C. A-Q, B-P, C-R, D-S
• D. A-S, B-Q, C-R, D-P

Answer 1

The correct option is A A-R, B-Q, C-P, D-S

Depression in freezing point because of the addition of glycol causes the decrease in freezing point which is used in car radiator to prevent the freezing of water present in a cars radiator.

Adding the salt causes the elevation in boiling point which then is useful for the proper boiling of the eggshells and egg.

Osmosis is the movement of water from the high concentration of water to its lower concentrations that are known as plasmolysis in plants.

Reverse osmosis is the opposite of osmosis in which water is moved against the concentration gradient to filter the water for drinking purpose.

Option A is the answer.
