Dry ice is solid carbon dioxide. instead of melting, solid carbon dioxide sublimes according to the equation: co2(s)→co2(g). when dry ice is added to warm water, heat from the water causes the dry ice to sublime more quickly. the evaporating carbon dioxide produces a dense fog often used to create special effects. in a simple dry ice fog machine, dry ice is added to warm water in a styrofoam cooler. the dry ice produces fog until it evaporates away, or until the water gets too cold to sublime the dry ice quickly enough. suppose that a small styrofoam cooler holds 15.0 l of water heated to 90 ∘c. calculate the mass of dry ice that should be added to the water so that the dry ice completely sublimes away when the water reaches 28 ?
