Study Notes
Intermolecular Attractions in Gases
- Intermolecular attractions between gas molecules are negligible, allowing them to behave independently.
- This indicates gases are mostly made up of empty space with minimal forces affecting molecular motion.
Volume of Gas Molecules
- The volume occupied by gas molecules is extremely small compared to the total volume of the gas itself.
- This implies that the volume of the gas is primarily attributed to the empty space between molecules, not the molecules themselves.
Total Energy During Collisions
- During collisions between gas molecules, the total energy remains constant.
- This signifies that collisions conserve energy, with kinetic energy potentially transforming into other forms without loss.
Kinetic Energy of Gas Molecules
- Gas molecules exhibit a range of kinetic energies that are dependent on temperature.
- Higher temperatures lead to increased average kinetic energy, illustrating that gas molecules move more vigorously at elevated temperatures.
Evidence of Random Motion
- Evidence for gas molecules being in constant, random, straight-line motion is observed through phenomena such as diffusion and effusion.
- The Brownian motion illustrates random movement, indicating varying velocities and directions within the gas phase.
