Dry ice is solid carbon dioxide. In its place of melting, solid carbon dioxide sublimes according to the subsequent equation: While dry ice is added to warm water, heat from the water reason the dry ice to sublime more quickly. The evaporating carbon dioxide produces a dense fog often utilized 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 in anticipation of it evaporates away, or until the water gets too cold to sublime the dry ice quickly enough. Presume that a small Styrofoam cooler holds 15.0 liters of water heated to 90.Utilized standard enthalpies of formation to calculate the change in enthalpy for dry ice sublimation. (The for is - 427.4). Compute the mass of dry ice that must be added to the water so that the dry ice completely sublimes missing when the water reaches 11. Presume no heat loss to the surroundings.
