Question
The table shows the boiling points for a range of substances.What type of vaporisation will take place with water at 80 °C?Evaporation as the temperature is below the boiling point.Boiling as the temperature is below the boiling point.Evaporation as the temperature is at the boiling point.Boiling as the temperature is at the boiling point.
Solution
The correct answer is "Evaporation as the temperature is below the boiling point." This is because water boils at 100 °C, so at 80 °C, it is not yet at the boiling point. Instead, some of the water molecules will have enough energy to escape from the liquid and become a gas. This process is known as evaporation.
