ii.ᴀ) A clinical thermometer has kink mark in its

stem.

Aɴsᴡᴇʀ;-

• In a clinical thermometer kink plays an important role. kink prevents the mercury present in the capillary to fall back in the BULB. So it SEPARATES the mercury at high temperature and cool mercury and allows the user to note the reading when the thermometer is taken out.

Qᴜᴇsᴛɪᴏɴ;-

ᴀ) Milk vans are carrying milk from the factory to the depots painted silver or white, give reason.

Qᴜᴇsᴛɪᴏɴ;-

iii. ᴀ) Which test is performed to confirm the release of carbon dioxide in a chemical reaction?

Aɴsᴡᴇʀ;-

• Carbon dioxide reacts with calcium hydroxide solution to produce a white precipitate of calcium carbonate. Limewater is a solution of calcium hydroxide. If carbon dioxide is bubbled through limewater, the limewater turns milky or cloudy white.
