Question

A liquid X has specific heat capacity higher than the liquid Y. Which liquid is useful as (i) coolant in car radiators, and (ii) heat reservoir to keep juice bottles without freezing?

Answer 1

(i) Liquid X is preferred as its specific heat capacity is more, hence it will be able to cool better.

(ii) Liquid X is preferred because of its high specific heat as it can impart a large amount of heat before reaching to its freezing point.
