a)Hydrogen has a much higher specific heat capacity than milk. What can you say about the specific heat capacity of hydrogen?b)wrap a cotton wool around a thermometer,will its temperature rise?Explain your answer c)if you are holding a metal nail with one of its end against a piece of ice,your hand soon becomes cold.Explain your observation.

    a)One should state the basis of units for specific heat capacity. On the basis of kJ/kg-K, that statement is true. It means, for a kg of material, hydrogen will go up in temperature less than milk for a specific heat added.
