Webeasy to heat up and cool down. Plain paper Timer Acetone Ethyl alcohol Water Procedure: 1. Soak a cotton ball in water. 2. In a piece of paper, swab the wet cotton ball. 3. Record how long will it take for the water to completely evaporate. 4. Repeat procedure using acetone and ethyl alcohol, respectively. 5. Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water. When the molecules of the liquid collide, they transfer energy to each other based on how they collide. When a …
