Question

(a) Is there any change in water level on adding salt into it?
(b) Which property of matter is depicted by the above figure?​

Answer 1

Answer:

No it will not increase or decrease the water level

This shows the property of solubility and the space between the partical of matter

Answer 2

Answer:

1)When sodium chloride dissolves in water to make a saturated solution there is a 2.5 per cent reduction in volume. ... The solubility of salt does not change much with temperature, so there is little profit in using hot water. The salt should be in small crystals and not in rocks or very fine powder.

2) Water level increases by adding salt and it shows solubility
