I bet many of you think that the ideal gas law must prohibit passing gas on the elevator. That's a very good guideline, but there are other important laws we must know! Let Professor Dave run you through the details.

TikTok's inversion filter reverses a facial selfie and shows you what your face looks like when its not reflected in a mirror. Or, in other words, how the world sees you and not what the mirror shows. Thus, the effect of this reversal is...

Why do we dance? We dance to music because of neural connections in our brain. These connections link the part that perceives music, the auditory cortex to the regions that help us move, the motor regions. We might have started creating...

Gases are everywhere, and this is good news and bad news for chemists. The good news: when they are behaving themselves, it's extremely easy to describe their behavior theoretically, experimentally and mathematically. The bad news is...

In this video, we will do an example calculation using the ideal gas equation of state, PV=nRT. [Solving for volume, V]

We don't live in a perfect world, and neither do gases - it would be great if their particles always fulfilled the assumptions of the ideal gas law, and we could use PV=nRT to get the right answer every time. Unfortunately, the ideal gas...

In this video Paul Andersen explains how the pressure, volume, amount, and temperature of an ideal gas are related. Absolute zero of a gas can be determined by varying the temperature and measuring the corresponding volume of a gas...

The buzzing sound that power lines produce is caused by corona discharge. Corona discharge is an electrical discharge that occurs when a fluid (like air) surrounding an electrically-charged conductor becomes ionized. In simple terms, its...

You might be familiar with the concept of self-harm, but it isn’t just physical. As it turns out, people can harm themselves through the anonymity of the internet.

We know a lot about ideal gases, including how to use all of the ideal gas laws. But we haven't talked much about how to do stoichiometry with gases. As it happens, we can do stoichiometry with gases not just using molar quantities, but...

We learned about ideal gases and the ideal gas laws, and we briefly touched on kinetic molecular theory, which puts these laws in context. But let's now go through this theory more rigorously, analyzing each postulate one at a time.

Our physical appearance is significantly influenced by our genes, which are inherited from our parents, who in turn receive their genetic material from their own parents. When your genetic makeup closely mirrors that of your...

In this video Paul Andersen explains how gases differ from the other phases of matter. An ideal gas is a model that allows scientists to predict the movement of gas under varying pressure, temperature and volume. A description of both...

Bridges. Bridges don't deal well with temperature changes. In order to combat this, engineers have come up with some work arounds that allow bridges to flex as they expand or contract. In this episode of Crash Course Physics, Shini talks...

We learned about ideal gases, as well as kinetic molecular theory, which explains the laws that govern ideal gases. But some of the postulates of this theory won't always hold true. When a gas is highly pressurized and/or very cold, it...

In this video Paul Andersen explains how the gas pressure is the force applied over the area of the container. It is also the change in momentum as gas molecules interact with the container and is uniform throughout the sample. Several...

Carrying a pole helps the walker increase their rotational inertia, which aids in maintaining stability while walking over the narrow rope. The pole also adds more weight below the center of gravity of the walker, which is another bonus...
