cont sec 3.2...

- Ex Prob 3.2 --> internal pressure is 0 for an ideal gas.

- Joule Experiment, but failed due to thermometer sensitivity (Ex. Prob 3.2).

- Expansion of CO2 gas (paintball gun demo) - tank gets cold.

- What is the value of the internal pressure is treated as real gas using van der Waals eq. (Ex. Prob 3.4)
