For many years drinking water has been cooled in hot climates by evaporating it from the surfaces of canvas bags or porous clay pots. How many grams of water can be cooled from 44 ∘C∘C to 25 ∘C∘C by the evaporation of 52 gg of water? (The heat of vaporization of water in this temperature range is 2.4 kJ/gkJ/g. The specific heat of water is 4.18 J/g⋅KJ/g⋅K.)
