Average Molecular Kinetic Energy An important property of molecules in a gas is their average kinetic energy This can be deduced from the ideal gas equations relating pressure, volume, tempe...
Bearings What are bearings? Bearings are a way of describing and using directions as angles They are specifically defined for use in navigation because they give a precise location and/or direction...
What is the sine rule? The sine rule allows us to find missing side lengths or angles in non-right-angled triangles It states that for any triangle with angles A, B and C Where a is the side opposi...
What is the Pythagorean theorem? Pythagoras’ theorem is a formula that works for right-angled triangles only It states that for any right-angled triangle, the square of the hypotenuse is equal to t...
What is volume? The volume of a 3D shape is a measure of how much 3D space it takes up A 3D shape is also called a solid You need to be able to calculate the volume of a number of common shapes How...
Kinetic Theory of Gases Equation Assumptions in Kinetic Theory Gases consist of atoms or molecules randomly moving around at high speeds The kinetic theory of gases models the thermodynamic ...
How does the 3D coordinate system work? In three-dimensional space we can label where any object is using the x-y-z coordinate system In the 3D cartesian system, the x- and y- axes usually represen...
Gas Laws v Kinetic Theory There is a scientific distinction between the gas laws and kinetic theory Gas Laws The gas laws are empirical in nature which means they are based on observation an...
Required Practical: Investigating Gas Laws Investigating Boyle's Law The overall aim of this experiment is to investigate the effect of Boyle's Law This is the effect of pressure on volume a...
