Solution
Common examples of condensation are: dew forming on grass in the early morning, eye glasses fogging up when you enter a warm building on a cold winter day, or water drops forming on a glass holding a cold drink on a hot summer day.
Wet clothes dry in sun due toevaporation - the water in wet clothes takes heat energy from sun and gets evaporated.
A goodexample of Transfer of heat would be heating a tin can of water using a Bunsen burner.
Examples of Solid to Gas (Sublimation) Dry Ice - Solid carbon dioxide is known as "dry ice" and sublimates at room temperature.
