1. Take some water in a glass. Add some pieces of ice to it. Observe for few minutes. What changes do you observe on the outer surface of the glass? You would observe formation of small drops of water on the outer surface of the glass. Why are these drops formed? Do they get formed if there is no ice in the glass?

2. Take a vessel filled with water. Keep it on a stove and heat it slowly. Observe for some time. Now cover the vessel with a plate. Remove the plate after a couple of minutes. Do you see any changes on the inner surface of the plate?
