Final Temp Inside the Tube:

Here comes the items, a seal glass tube which can squeeze the air to a small volume and increase the pressure inside the tube to make the temperature rise enough to burn the cotton.

Since smaller volume with same amount of molecules gives higher pressure, the higher pressure cause the higher temperature. Pretend we do this lab pretty fast that almost 0 heat is losing. This means we can use the relationship between temperature and value to calculate the final temperature. The final temperature is 1565.6 degree F.

Activphysic 6 Questions:

Here are six question which involve Isobaric, Isothermal ,and  Isochoric.

Calculation:

Isobaric means constant pressure

Isothermal means constant temperature

Isochoric means constant volume

Using Ideal Gas Law:

Since Energy (work or heat) remand the same at initial and final, the final value and pressure can be easily solve when there are only one unknown.
