Some statements include a misconception. Name the process, then check the whole claim in the feedback. Decide whether it’s evaporation or condensation.
Water left in a shallow dish on a windowsill is gone from the dish after a few days.
Correct! The water changed from liquid to a gas — that’s evaporation. Evaporation is the change of state from a liquid to a gas.
Not quite. The water didn’t change from a gas to a liquid; it changed from a liquid to a gas. That’s evaporation, not condensation.
A cold mirror in a steamy bathroom comes out covered in tiny droplets of water.
Correct! The water vapour in the air changed from a gas to liquid droplets — that’s condensation. Condensation is the change of state from a gas to a liquid.
Not quite. The water changed from a gas to a liquid, not the other way. That’s condensation, not evaporation.
The white cloud you can see above a boiling kettle is water vapour.
You’re right about the change. The white cloud is formed by condensation (gas to liquid). But the statement itself is wrong — the cloud is not water vapour. Water vapour is invisible. The cloud is actually tiny liquid water droplets formed by condensation.
Not quite. The white cloud is not water vapour; it’s liquid droplets formed by condensation. The change here is condensation (gas to liquid), not evaporation. Water vapour is invisible — the cloud is made of liquid water.
Water only turns into water vapour on a hot day or when it boils.
You’re right about the change. Turning into water vapour is evaporation (liquid to gas). But the statement is wrong — water evaporates at all temperatures, not only when it’s hot or boiling. Evaporation happens even on a cold day.
Not quite. The change described is water turning into vapour, which is evaporation (liquid to gas), not condensation. Also, water evaporates at all temperatures, not just when it’s hot — the statement is false.
Finishing the four cards completes this section. You can now name the process from the direction of the change (evaporation = liquid → gas, condensation = gas → liquid), and tell water vapour (invisible) from the visible cloud it makes (liquid droplets).
