Problem

A mass of 50g of water in a closed vessel, with surroundings at a constant temperature takes 2 minutes to cool from 30∘C30^{\circ}\text{C} to 25∘C25^{\circ}\text{C}. A mass of 100g of another liquid in an identical vessel with identical surroundings takes the same time to cool from 30∘C30^{\circ}\text{C} to 25∘C25^{\circ}\text{C}. The specific heat of the liquid is :
