... Evaporation Of Alcohol Aim: To see how one variable affects the speed at which alcohol evaporates. Background Information: I already know that forces of attraction between particles in a liquid are weaker than those in a solid. Liquids cannot be compressed because there is no space between the particles. Particles in a gas move quickly in all directions. Gases are easily compressed because there is more space between the particles. When a substance is heated it has more energy to escape the forces of attraction between the particles. I know that alcohol is very volatile compared to water. When a liquid is heated it will evaporate and become a gas. Many things affect the rate of evaporation: Room temperature Liquid temperature Surface temperature Surrounding wind speed Surface area of alcohol Concentration of alcohol Barrier of container alcohol is in. Prediction: I think that the 70 C experiment will make the most alcohol evaporate
