Study Notes
Boyle's Law
- States that the product of volume and pressure is constant for a specific mass of gas at a fixed temperature.
- Describes the inverse relationship between volume and pressure of a gas.
- Key equation: pV=k, where p is pressure, V is volume and k is a constant.
States of Matter
- Solid: Has a fixed shape and volume, strong attractive forces, and vibrates only in position.
- Liquid: Doesn't have a fixed shape but has a fixed volume, weaker attractive forces, and moves freely but stays close together.
- Gas: Has no fixed shape or volume, small attractive force, moves freely, and exists as loosely packed neutral molecules or atoms.
- Plasma: Has no fixed shape or volume, contains positive nuclei and negative electrons, and exists as a state of matter with free ions.
Repulsive and Attractive Forces
- Opposite charges are attracted to each other, hence the attraction forces occur when atoms come close to each other.
- Repulsion occurs when electron clouds of molecules touch.
- Cohesive forces: are attractions between like molecules.
Intermolecular Forces
- Intermolecular forces are responsible for the aggregation of molecules in gases, liquids, and solids.
-
Induced dipole-induced dipole or dispersion forces (London forces):
- occur between non-polar molecules.
- induced polarity arises due to the asymmetry of electron distribution around the nucleus.
- bond energy is 1-7 kcal/mole.
Hydrogen Bonding
- Occurs between a molecule containing a hydrogen atom and a strongly electronegative atom like Fluorine, Oxygen or Nitrogen.
- A type of intermolecular force.
- The bond energy is about (1-7) kcal/mole, which makes it a relatively strong type of intermolecular force.
