    1672 J

    Explanation:

    We are supposed to find out the energy released by water when cooled from 50° C to 30°C.

    We have the relation that,

    H=msΔT

    Information is given that s=4.18 J / g*°C,

    m=20.0 g,

    and ΔT is - 20° C.

    Hence by substituting we get,

    H=-20*20*4.18

    (minus symbol represents that energy is being released)

    1672 J is release when water is cooled from 50° C to 30°C.
