For many years drinking water has been cooled in hot climates by evaporating it from the surface of canvas bags or porous clay pots. how many grams of water can be cooled from 40 ∘c to 20 ∘c by the evaporation of 43 g of water? (the heat of vaporization of water in this temperature range is 2.4 kj/g. the specific heat of water is 4.18 j/g⋅k.)
