Rate of evaporation
In this activity students investigate the process of evaporation and use a temperature sensor to record temperature changes during evaporation of water and alcohol.
Activity Evaporation of water (demo)
In this activity students investigate process evaporation. They use a temperature sensor to record temperature changes during evaporation of alcohols. They investigate how the molecular mass of evaporating alcohol affects the rate of evaporation.
