Question
Vinu dissolves 50 g of sugar in 250 ml of hot water, Sarath dissolves 50 g of the same sugar in 250 ml of cold water. Who will get a faster dissolution of sugar? and Why?
Solution
Vinu will get a 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 an increase in temperature.
