    Answer: 17.9 joules

    Explanation:

    The quantity of Heat Energy (Q) required to heat solid silver depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

    Thus, Q = MCΦ

    Given that,

    Q = ?

    Mass = 3.02g

    C = 0.24J/g°C

    Φ = (Final temperature - Initial temperature)

    = 47°C - 22.3°C = 24.7°C

    Then, Q = MCΦ

    Q = 3.02g x 0.240J/g°C x 24.7°C

    Q = 17.9 Joules

    Thus, 17.9 joules of heat isrequired.
