WorksheetsLesson 2.3 Changing State - Condensation
Total questions: 12
Worksheet time: 6mins
1. Think about the cup that was not in the bag. Where do you think the water molecules came from that formed the moisture on this cup?
2. A student made a claim that the water leaked from the inside of the cup and got on the outside surface of the cup. What evidence in this experiment using the plastic bag proves that the student has a false claim?
3. In this experiment, there was hot, liquid water in the lower cup. Do you think there was water vapor in the upper cup? If so, where do you think it came from?
4. In the animation, you saw that the upper cup had water vapor in it. Use what you saw in the animation to explain how the water vapor in the upper cup changed to liquid water on the inside surface of that cup.
5. When you compare the two upper cups, what do you notice about the amount of liquid water that condensed on the inside surface of each?
there was the same amount of liquid water inside both upper cups
there was no liquid water inside either upper cup
there was more liquid water inside the room-temperature cup
there was more liquid water inside the ice-covered cup
6. Why do you think adding ice caused more condensation in that cup?
Fogging up a cold window When you breathe on a cold window in the winter, the window gets tiny droplets of moisture on it or “fogs up.” Using what you know about condensation, explain why you think the cold window gets foggy. (Hint: There is water vapor in your breath.)
Warm breath in cold air When you breathe out in the winter, you see “smoke,” which is really tiny droplets of liquid water. Using what you know about condensation, explain why you think this happens.
Energy from the sun causes water to evaporate from the land and from bodies of water. As this water vapor moves high into the air, the surrounding air cools it, causing it to condense and form ________________.
runoff
evaporation
clouds
groundwater
What color is the condensed water, also called condensation, that collects on the inside of the top cup?
colorless
red
If you were stranded on an island and only had saltwater, how could you make water to drink?
How do you feel about what you have learned in this lesson?
😊 Great! I am confident that I understand the material.
🙂 Good, but I still have a question. I will ask the teacher about it by email or in class.
😐 OK, but I need more practice. I will read through the lesson and re-watch some of the videos.
🤨 I need help. I will review the lesson and make a list of topics that are confusing to me. I will reach out to the teacher for help.
