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...

What is an arc? An arc is a part of the circumference of a circle It is easiest to think of it as the crust of a single slice of pizza The length of an arc depends of the size of the angle at the c...
Avogadro, Molar Gas & Boltzmann Constant Avogadro's Constant The atomic mass unit (u) is approximately the mass of a proton or neutron = 1.66 × 10-27 kg This means that an atom or molecu...
Work Done by a Gas When a gas expands, it does work on its surroundings by exerting pressure on the walls of the container it's in This is important, for example, in a steam engine where exp...
Ideal Gas Equation An ideal gas is a specific type of gas which: Has molecules with negligible volume Collisions which are elastic Cannot be liquified Has no interactions between the molecul...
Ideal Gas Laws The ideal gas laws are the experimental relationships between pressure (P), volume (V) and temperature (T) of an ideal gas The mass and the number of molecules of the gas is a...
