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...

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...

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...

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.

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

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...

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...

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...

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 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...

How can bottles and balloons help explain the different laws that govern gas? See how Boyle's Law, Charles' Law, and Avogadro's Law help us understand the laws that govern gas properties.
