    Answer:

    Water.

    Explanation:

    This means:

    1) For the temperature of water to raise at any point to the next degree by 1°C, will require a specific heat capacity of  4.184  J/Kg°C

    2) For the temperature of wood to raise at any point to the next degree by 1°C, will require a specific heat capacity of  1.760  J/Kg°C

    Note that: specific heat is directly proportional to energy, therefore the higher the heat capacity, the higher the energy.

    4.184  J/Kg°C is higher than 1.760  J/Kg°C, hence WATER needs more energy.
