2.1 Simple kinetic molecular model
of matter (Thermal Physics)
- 2.1.1 States of matter
- state the distinguishing properties of
solids, liquids and gases
- state the distinguishing properties of
solids, liquids and gases
- 2.1.2 Molecular model
- describe qualitatively the molecular
structure of solids, liquids and gases
Annotations:
- in terms of the arrangement, separation and motion of the molecules
- relate the properties of solids, liquids and gases to
the forces and distances between the molecules and
to the motion of the molecules
- interpret the temperature of a gas in
terms of the motion of its molecules
- describe qualitatively the pressure of a gas
in terms of the motion of its molecules
- explain pressure in terms of the
change of momentum of the particles
striking the walls creating a force
- explain pressure in terms of the
change of momentum of the particles
striking the walls creating a force
- show an understanding of the
random motion of particles in a
suspension as evidence for the
kinetic molecular model of matter
- describe this motion (sometimes known as Brownian motion)
Annotations:
- in terms of random molecular bombardment
- show an understanding that massive
particles may be moved by light,
fast-moving molecules
- describe this motion (sometimes known as Brownian motion)
- describe qualitatively the molecular
structure of solids, liquids and gases
- 2.1.3 Evaporation
- describe evaporation
Annotations:
- in terms of the escape of more-energetic molecules from the surface of the liquid
- demonstrate an understanding of how ... influence evaporation
- temperature
- surface area
- draught over a surface
- temperature
- relate evaporation to
the consequent
cooling of the liquid
- explain the cooling of a
body in contact with an
evaporating liquid
- describe evaporation
- 2.1.4 Pressure changes
- Describe
qualitatively, in terms
of molecules, the
effect on the
pressure of a gas of:
- a change of temperature at constant volume
- a change of volume at constant temperature
- a change of temperature at constant volume
- recall and use the equation pV
= constant for a fixed mass of
gas at constant temperature
- Describe
qualitatively, in terms
of molecules, the
effect on the
pressure of a gas of:
