This Video Explains Substantive and Procedural Law

It explains solution and its properties. It also talks about the concentration of a solution.

Drugs of all varieties are very interesting from a biochemical standpoint, as they produce an incredible array of physiological effects. These effects are due to the shape of each molecule, which determines the cellular components they...

The video explains the concept of density, which is the mass of a substance in one cubic meter of it. The equation for calculating density is explained as well as illustrated with a simple example, where a glass block is weighed to find...

It describes the standard enthalpy of combustion. It explains the enthalpy of atomisation and bond enthalpy and discusses the enthalpy of solution and lattice enthalpy.

Now that we know about the solubility product, it's time to learn about some applications for this concept. First, we can use this to predict whether precipitation will occur in a particular solution, and take measures to cause or...

U-values measure how effective a material is an insulator. The lower the U-value, the better the material is as a heat insulator. For example, a cavity wall has a u-value of 1.6, so most of the heat inside the house will stay in the...
