Explain why adding ice to a drink can cause water droplets (condensation) to appear on the outside of the glass. If you need help developing your answer, think about how farmers can use water to keep oranges warm in cold weather, or about the change in energy you measured during the melting of ice to water.

When the hot air comes in contact with the cold glass, heat is transferred from the hot air to the cold glass. The loss of heat in the surrounding air causes the water vapor by the glass to lose energy. Once energy is lost, the water vapor condenses into liquid on the glass.

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).
