Investigating Gas Pressure and Volume Boyle's Law relates pressure and volume at constant temperature This investigation is one valid example of how this required practical might be tackled, others...
Ideal Gas Equation When calculating for gases, assume that the gas is an?ideal gas The?three gas laws?(explained below) can be combined to create one equation in terms of pressure, volume, temperat...
Kinetic Theory of Gases Equation Gases consist of atoms or molecules randomly moving around at high speeds The kinetic theory of gases models the thermodynamic behaviour of gases by linking the?mic...
Absolute Zero On the thermodynamic (Kelvin) temperature scale, absolute zero is defined as: The lowest temperature possible. Equal to 0 K or -273.15 °C It is not possible to have a temperature lowe...
Internal Energy Energy can be classified into two forms: kinetic or potential energy The molecules of all substances contain both kinetic and potential energies Kinetic energy is due to the speed o...
