    Heat energy is supplied to materials and can cause an increase in temperature of the material. the formula is as follows

    H = mcΔt

    where H - heat energy

    m - mass of material

    c - specific heat

    Δt - change in temperature - 40.0 °C - 22.5 °C = 17.5 °C

    substituting the values

    H = 175 g x 0.234 Jg⁻¹°C⁻¹ x 17.5 °C

    H = 716.6 J

    716.6 J is required
