States of Matter & Temperature - A Level Physics

This resource is a complete lesson that covers States of Matter & Temperature for the OCR A Level Physics A course. However, it is useful for other exam boards too.

This lesson teaches the following content:
-thermal equilibrium
-absolute scale of temperature (i.e. the thermodynamic scale) that does not depend on property of any particular substance
-temperature measurements both in degrees Celsius (°C) and in kelvin (K)
-T(K) ≈ θ(°C)+273
-solids, liquids and gases in terms of the spacing, ordering and motion of atoms or molecules
-simple kinetic model for solids, liquids and gases
-Brownian motion in terms of the kinetic model of matter and a simple demonstration using smoke particles suspended in air
-internal energy as the sum of the random distribution of kinetic and potential energies associated with the molecules of a system
-absolute zero (0 K) as the lowest limit for temperature; the temperature at which a substance has minimum internal energy
-increase in the internal energy of a body as its temperature rises
-changes in the internal energy of a substance during change of phase; constant temperature during change of phase.

This lesson includes:
-A full presentation including 4 example questions with worked solutions.
-A worksheet with model answers, perfect to set as homework.
-Clear visual aids and diagrams to simplify complex concepts.
-Editable PowerPoint and Word document for easy customisation.
