2025-2026 Objectives For Gasses

Essential Questions (EQ4): Do and/or how do basic particles interact - Stay same?

Each student will be able to:

1. Explain the kinetic molecular theory (i.e. ideal gas condition) with respect to gas phase and what the major gas parameters mean (T, P, V, and n). (Hint: Gas behavior video)

2. Using the kinetic molecular theory, explain the relationship (including doing calculations) between:

• Pressure (P) and volume (V) (Boyle's law)
• Pressure (P) and (T) temperature (No-Name i.e. Gay-Lussac's Law )
• Volume (V) and (T) temperature (Charles' law)
• Number of particles (n) and volume (V) of in a gas sample (Avogadro's hypothesis).
  

3. Explain the relationship between temperature and average kinetic energy.

4. Perform calculations using the ideal gas law including the gas constant, R.

As part of this, understand the molar volume (i.e. volume of a mole of gas) is a constant for any gas at a specific temperature and pressure. Specifically for 273K and 1.0 atm (that is what STP stands for Standard Temperature and Pressure)), the molar volume is 22.4L per 1.0 mole.
