# Charles Law Concept Questions.

I included Charles law lab procedures for reference and questions are in MS words format.

(See attached files for full problem description)

---
1. When the flask is submerged in the boiling water, what is happening to the gas inside the flask?
2. Compare the pressure of the gas outside the flask with the pressure of the gas inside the flask once the gas inside the flask reaches the temperature of the boiling water?
3. Why did the water enter the flask when it went from a high temperature to a lower temperature?
4. What is the relationship between the volume of the water entering the flask and the volume decrease of the gas inside the flask? Explain.
5. Why were the water levels made to coincide before the flask was removed?
6. How does the composition of the gas (air) in the flask change when it is suspended over the boiling water?

I want answers in complete sentences and the answers have to be perfectly correct.
1. When the flask is submerged in the boiling water, what is happening to the gas inside the flask?
The air molecules are increasing in energy due to the increased temperature. As they increase in energy, they move faster. As they move faster, they spread apart further, taking up more space. The effect is observed as an expansion or increase in volume. In addition, the temperature of the gas inside the flask is equilibrating to 100 degrees Celsius.
2. Compare the pressure of the gas outside the flask with the pressure of the gas inside the flask ...
