    Answer is: 100,464 kJ energy are absorbed.

    m (water) = 800,0 g.

    T₁ = 20°C.

    T₂ = 50°C.

    ΔT = T₂ - T₁.

    ΔT = 50°C - 20°C.

    ΔT = 30°C.

    c (water) = 4,186 J/g·°C.

    Q = m · c · ΔT.

    Q = 800 g · 4,186 J/g·°C · 30°C.

    Q = 100464 J = 100,464 kJ.

    c - specific heat of water.
