- Write a summary statement about each of the 6 examples.
- Write 1 question you have about each example.
- When finished, go to each Lab Table and write your summary statement and question on the document.

- A balloon with a volume of 3 L at 25 C is heated to 35 C. Make a drawing of the balloon before and after heating. Then, determine the new volume?
- A 2 L bottle of gas has a pressure of 1.5 atms. The pressure is raised to 1575 mmHg. Make a drawing of the bottle before and after the pressure is raised. Then, determine the new volume?

- Make a list of the given values
- Use the list to determine which gas law to use
- Before solving, predict if the volume will go up or down
- Before solving, isolate the gas law for the new volume
- Plug in your values and solve for the new volume
