You are on a picnic and you make tea for yourself and your friend. However, your friend has gone out to bring something for you. You observed that the fire (that you ignited for making tea) has heated two nearby blocks of stones – one of sand stone and other of granite – to `90^(@)C`. Both blocks have nearly same mass but granite has higher specific heat than marble. To keep the tea hot for your friend you decided to place the tea pot on one of the stones. Which stone will you choose – granite or marble?
