States of matter

Gases and the Ideal Gas EquationSign up

explain the origin of gas pressure from molecular collisions with the walls · state the assumptions of the ideal gas (kinetic) model · recall and use the ideal gas equation pV = nRT · explain the limitations of the ideal gas model and conditions for real-gas deviation

Metallic Bonding and Lattice TypesSign up

understand that metals consist of giant lattices of metal ions in a sea of delocalised electrons · know that metallic bonding is the strong electrostatic attraction between metal ions and the delocalised electrons · be able to use the models in 3.20 and 3.21 to interpret simple properties of metals, including electrical conductivity and high melting temperature
