The latent heat of fusion for water is 33.5 × 104 J/kg, while the latent heat of vaporization is 22.6 × 105 J/kg. What mass m of water at 0 °C must be frozen in order to release the amount of heat that 2.32 kg of steam at 100 °C releases when it condenses?

    λ=3.35•10⁵ J/kg
    r=2.26•10⁶J/kg
    Q₁=Q₂
    λm₁=rm₂
    m₁=rm₂/λ= 2.26•10⁶•2.32/3.35•10⁵=15.65 kg
