Evaporation and Boiling
Chemistry ⇒ States of Matter
Evaporation and Boiling starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Evaporation and Boiling.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 7
A beaker of water is heated until bubbles form throughout the liquid. What is this process called?
A student leaves a bowl of water on a windowsill. After a few days, the water level drops. What process is responsible for this?
Describe one everyday example of evaporation.
Describe what happens to the temperature of a liquid while it is boiling.
A beaker of water is heated until bubbles form throughout the liquid. What is this process called?
A student leaves a bowl of water on a windowsill. After a few days, the water level drops. What process is responsible for this?
A sealed container of water is placed in a room at 25°C. After several days, the water level remains unchanged. Explain why evaporation does not occur in this situation.
A student notices that a wet cloth dries faster on a windy day than on a calm day. Explain the reason for this observation.
