Question

1. Vinu dissolves 50 g of sugar in 250 ml of hot
water, Sarath dissolves 50 g of same sugar
in 250 ml of cold water. Who will get
faster
dissolution of sugar? and Why?​

Answer 1

Answer:

Vinu

Explanation:

Vinu will get faster dissolution of sugar. Because Vinu dissolves 50 g of sugar in 250 ml of hot water, whereas Sarath dissolves 50 g of sugar in 250 ml of cold water. Solubility of a solid in liquid increases with increase in temperature.

Hope the answer is correct!

Answer 2

Vinu

This is because the temperature of hot water>temperature of cold water & solubility ∝ temperature.

Higher the temperature,more will be the solubility.
