Understanding the polarity of a molecule is critical to understanding how that molecule interacts with its surroundings. But to understand polarity, one must first...
Playlist - Full Course! Start to Finish!
This is it! Here is the entire course IN ORDER!
Now that we understand what makes a molecule polar or non-polar, we can talk about the kinds of physical interactions they can manifest with each other. Will it be the...
The final intermolecular force is a strong sub-species of dipole forces called the hydrogen bond. No, it’s not a chemical bond. It’s another physical...
Gases. Variable volume and variable shape make them the neatness state of matter. A lot of early understanding of chemistry was established through the study of gases...
There are quite a few units to measure pressure in. And quite a few devices that can measure it. Ever think about a barometer? You will.
Pressure is an interesting topic in itself, but DIFFERENCES in pressure are downright fascinating. Pressurized cabins, straws, lungs, etc. are all great examples of...
Pressure continues to astound us. Today we focus on the vapor (gases) coming off of liquids. What does this vapor pressure do? How does it affect boiling points...
Gas laws! Though kinetic molecular theory is great at explaining what happens, the mathematical ramifications are left to the laws. We’ll start with Boyle’s...
The Gas Laws continue. Charles’ Law deals with the relationship between TEMPERATURE and VOLUME. It’s a direct relationship, meaning the volume will increase...
Our journey through gas laws continue with Gay-Lussac. The relationship between pressure and temperature is pretty straight forward. If you know it isn’t a smart...
