Study Notes
Real Gases
- Real gases deviate from ideal gas behavior due to intermolecular forces and finite molecular volume.
- Real gases are more compressible than ideal gases because attractive forces between the molecules cause them to occupy less volume.
Latent Heats
- Latent heat of vaporization is the amount of heat absorbed when a liquid vaporizes or released when a vapor condenses.
- Latent heat of fusion is the amount of heat absorbed when a solid melts or released when a liquid freezes.
- For water at 0°C, the latent heat of fusion is approximately 80 calories per gram (1436 calories per mole).
Le Chatelier's Principle
- Le Chatelier's principle states that when a system at equilibrium is subjected to a change in conditions, it will readjust to minimize the effect of the change.
- This principle can be applied to explain the behavior of real gases.
Mesophases
- Mesophases are intermediate states of matter between solids and liquids, with properties of both.
- Molecules that form mesophases typically have these characteristics:
- Organic
- Elongated shape
- Rigid structure
- Possess strong dipoles and are easily polarizable.
Three-Component Systems
- In a three-component system, the composition can be represented by a triangular phase diagram.
- Each corner of the triangle represents a pure component (A, B, or C).
- The lines joining the corners represent two-component mixtures.
- The area inside the triangle represents all possible combinations of the three components.
