Specific heat of  a  substance is the amount of heat required to raise the temperature of unit mass of the substance by one unit .
1.If the specific heat of a substance is high at that time the substance need more    energy to rise the temperature of if it.
2.It takes much timr to cool and it takes much time to become hot.so that, even      on a hot day afterremoving the water melon from refrigerator it stays cool for        longer time. Because it contains more water and the specific heat of water is        high.
