# Introduction for Module 8 – Gas Relationships

Textbook: Open Stax Chemistry 2e

Suggested Reading: Chapter 9.1-9.2

Learning Objectives:

- Describe the relationship between the properties of gases: Pressure, Temperature, Volume, Moles
- Explain the assumptions made by assuming ideal gas behavior
- Calculate properties of ideal gases using various gas laws
- Explain the significance of the ideal gas constant, R

- When a sample is held at constant volume and number of moles (aka. sealed, rigid) increasing temperature by heating will result in an increase in pressure. Figure 9.10, The effect of temperature on gas pressure by Open Stax is licensed under CC BY 4.0.
- When ideal gas behavior is assumed, the identity of a gas has no impact on its standard molar volume - the volume mole of that gas occupies at 0 oC and 1 atm. Figure 9.18, Regardless of its chemical identity by Open Stax is licensed under CC BY 4.0.
