Текст на Статията
- Yes, Margaux. I am very excited to ride at the hot air balloon because it's my first time.
- Hey! Casey, Are you excited to ride at the hot air balloon?
- Casey, did you know why does a hot air balloon expand when heated?
- When the air inside theballoon is heated, themolecules in the air begin to move around and spread out, and the air becomes less dense. The surrounding, colder air falls beneath the hot air. This forces the warm air upward, which pushes the balloon up with it.
- It is an example of Charles's Law because it is stated in this law that if the temperature is increased, the volume also increased and that's whathappened in Hot Air Balloon.
- OMG, this is fun!!
- Now, that you know why the air balloon expand when it is heated. What do you think type of gas law is Hot Air Balloon under?
- One day, Margaux and Casey decided to go to a hot air balloon festival to spend quality time and create happy moments with each other. They were very excited because they weretogether and it will also help them understand their teacher's lesson for next week about Charles's Law.
- Casey, did you know that in 1787, a French physicist, Jacques Charles observed and discovered the effect of temperature on thevolume of a gas?
- Yes, and he found that various gases expanded by the same fractional amount when heated through the sametemperature interval.
- The two friends go to the festival and talked about the topic that they'll discuss soon in their Science class. Margaux asked Casey why does hot air balloon expands when there is fire.
- Me too, I've learned a lot today and I think that were ready in our next lesson in Science class.
- They continue discussing their topic. This time Casey asked Margaux what type of gas law is Hot Air Balloon under and why it is under this gas law.
- This time Margaux and Casey talked about who discovered Charles's Law and what he observed,discovered, and found.
- The two friends went home happy, they both learned a lot that day and are ready for their next lesson in their Science class.
- I am very happy and I really enjoy this day.
- Margaux and Casey went home.
