The rates of cooling of two different liquids put in exactly similar calorimeters and kept in identical surroundings are the same if

Equal masses of two liquids are filled in two similar calorimeters. The rate of cooling will

Equal masses of two liquids are filled in two similar calorimeters. The rate of cooling will

A mass of 50g of water in a closed vessel, with surroundings at a constant temperature takes 2 minutes to cool from 30^(@)C to 25^(@)C . A mass of 100g of another liquid in an identical vessel with identical surroundings takes the same time to cool from 30^(@) C to 25^(@)C . The specific heat of the liquid is: (The water equivalent of the vessel is 30g.)

Two spheres of same material and radius r and 2r are heated to same temperature and are kept in identical surroundings, ratio of their rate of loss of heat is

Two spheres of same material and radius r and 2r are heated to same temperature and are kept in identical surroundings, ratio of their rate of loss of heat is

Equal masses of two liquids are filled in two identical calorimeters. The rate of cooling will

A sphere and a cube of equal volumes both are made of iron and have similar surface. If both are cool in identical surrounding, at a lower temperature, then the ratio of the initial rates of loss of heat is

The rate of expansion for the same liquid differs greatly in different temperature ranges.
