    3J

    Explanation:

    The following were obtained from the question:

    M = 5g

    T1 = 25.0°C

    T2 = 27.5°C

    C = 0.24 J/g°C

    Q=?

    Using the following equation Q = MCΔT to solve for the energy need, we have:

    Q = MCΔT

    Q = 5 x 0.24 x (27.5 - 25)

    Q = 5 x 0.24 x 2.5

    Q = 3J
