Mechanical Properties of matter: State, analyse and explain change of state due to molecular forces
Subject outcome
Subject outcome 5.3: State, analyse and explain change of state due to molecular forces
Learning outcomes
- Describe and distinguish between intermolecular bonding and intramolecular forces.
- Identify the types of intramolecular forces: hydrogen bonding and van der Waals forces and illustrate with examples.
- Explain the physical state of matter with reference to intramolecular forces and illustrate with examples.
- Use boiling point of group- 5, 6, 7 hydrides to differentiate between the strength of hydrogen and van der Waals forces and the effect of mass on the boiling point.
Unit 1 outcomes
By the end of this unit you will be able to:
- Describe and identify intermolecular bonding.
- Describe and identify intramolecular forces.
- Describe and identify hydrogen bonding.
- Describe and identify van de Waal’s forces.
Unit 2 outcomes
By the end of this unit you will be able to:
- Understand and identify that intramolecular forces act within physical states of matter.
- Understand and identify the effect molecular mass has on boiling point.
- Understand and identify that the strength of both hydrogen bonds and van der Waals forces affect the boiling point of elements in groups [latex]\scriptsize \displaystyle 15-17[/latex].
