    To calculate the specific heat capacity of an object or substance, we can use the formula

    c = E / m△T

    Where

    c as the specific heat capacity,

    E as the energy applied (assume no heat loss to surroundings),

    m as mass and

    △T as the energy change.

    Now just substitute the numbers given into the equation.

    c = 2000 / 2 x 5

    c = 2000 / 10

    c = 200

    Therefore we can conclude that the specific heat capacity of the block is 200 Jkg^-1°C^-1
