    Complete question :

    Use the equation qliquid = m × c × ΔT to calculate the heat gained by the cold liquid. Use the specific heat for the liquid you selected.

    m = 248.9 g ; T = 72.6°C ; C = 3.73 j/g°C

    Use the equation qwater = m × c × ΔT to calculate the heat lost by the hot water. Show your work using the problem-solving method shown in previous rubrics.

    M = 237 g ; T = 41.2°C ; C = 4.184 j/g°C

    Answer:

    Quantity of heat gained = 67401.6 Joules

    Quantity of heat lost by hot water = 40854.25 Joules

    Explanation:

    The heat gained by cold liquid :

    Q = m × c × ΔT

    m = 248.9 g ; T = 72.6°C ; C = 3.73 j/g°C

    Q = 248.9 * 3.73 * 72.6

    Q = 67401.6 Joules

    Quantity of heat gained = 67401.6 Joules

    Heat lost by hot water :

    m × c × ΔT

    M = 237 g ; T = 41.2°C ; C = 4.184 j/g°C

    Q = 237 * 41.2 * 4.184

    Q = 40854.25 Joules

    Quantity of heat lost by hot water = 40854.25 Joules
