In this video, you'll learn the fundamentals of gas laws and how they describe the behavior of gas molecules. Students will gain a clear understanding of key variables—pressure, volume, temperature, and moles—and their significance in...

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...

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...

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...

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.

Hank uses a favorite subject of the YouTube community - the potato gun - to teach us about the principles of pneumatics, which use the potential energy of compressed gas to do work in lots of useful machines every day.

Have you ever heard of a Perpetual Motion Machine? More to the point, have you ever heard of why Perpetual Motion Machines are impossible? One of the reasons is because of the first law of thermodynamics! In this episode of Crash Course...

In this video Paul Andersen explains how the second law of thermodynamics applies to reversible and irreversible processes. In a reversible process the net change in entropy is zero. In and irreversible process the entropy will always...

Roller coasters give people the opportunity to experience physics in dramatic ways. In this episode of SciShow, we break down how physics work on roller coasters to give you the ride of your life!

Roller coasters give people the opportunity to experience physics in dramatic ways. In this episode of SciShow, we break down how physics work on roller coasters to give you the ride of your life!

This is a science lesson in which the relationship between the pressure and temperature of a gas at a fixed volume is investigated. The video uses visual aids to demonstrate how particles with kinetic energy collide with container walls...

This is a lecture video explaining the mathematical relationship between the pressure and volume of a gas when it is at a constant temperature and has a fixed mass. The video discusses how the pressure and volume of a gas are inversely...

Group human behavior can be largely explained by physics. In fact, crowds, traffic and pedestrian behavior can be modeled using using principle from physics.



Everyone in a crowd has their own...

This video is a lesson about the physics of rockets and how engineers design and build them. The teacher explains concepts such as Newton's three laws of motion, the role of forces in rocket propulsion, the importance of thrust, weight,...

This is how a dipping bird toy/ drinking bird / dunking bird works explained. Explained with animations. A drinking bird works by cooling of the head via. evaporative cooling. That will cause the liquid (dichlormethane) inside the...

Time may be a human construct but that hasn't stopped physicists from perfecting it. Read More: JILA’s 3-D Quantum Gas Atomic Clock Offers New Dimensions in
