Learn the basics about the law of the conservation of mass, when learning about properties of matter. The Law of Conservation of Mass says that in chemical reactions no matter is lost or gained. The law of conservation of mass means that...

When you eat a burrito, where does all that matter go? What about when matter changes phases, does any matter appear or disappear? When we talk about this sort of stuff, reality sometimes goes against our intuition, so we'd better make...

This engaging program explains how chemical reactions can be described and written. Special emphasis is focused on how chemical reactions involve the rearrangement of atoms, but not the overall change in mass (Law of the Conservation of...

So when water evaporates, what happens? Where does that water go? Does just vanish? Is it no more? Can matter every just go away? Well, the answer is no, it can't. But it can LOOK like it does. In this episode of Crash Course Kids,...

Everything in our universe has mass - from the smallest atom to the largest star. But the amount of mass has remained constant throughout existence even during the birth and death of stars, planets and you. How can the universe grow...

SUMMARY

The law of energy conservation may be the most fundamental law in physics. It says that overall energy is always conserved. It can never be created nor destroyed - it can only change form. But this law...

When the elimination method is used to solve a system of linear equations, viewing the geometrical changes that happen to the system during this process can give insight into the mechanisms which underlie the logic behind the algebraic...

On today's episode I interview Shana from California. Don't be typical tourist when you visit the Golden State. Shana will show us 3 things that only Californians know so that you can experience this amazing state like a local!

Political scientist Ronald Inglehart, World Values Survey director at the University of Michigan in Ann Arbor, says greater economic growth, democratization and social tolerance in 45 of 52 countries for which substantial time series...

Headache - Read by Michael Rosen from The Hypnotiser<br/>

Paul Andersen explains how energy is conserved within a system. In both macroscopic and microscopic collisions the amount of energy before the collision is equal to the amount after. He then defines heat as energy transfer between...

In this video Paul Andersen explains how the energy, charge, and momentum in a system is conserved over time.

In this video Paul Andersen explains how the continuity equation is an application of conservation of matter in a fluid. The continuity equation may apply to either mass or volumetric flow. Example problem and examples are included.

Learn the basics about the law of the conservation of mass, when learning about properties of matter. The Law of Conservation of Mass says that in chemical reactions no matter is lost or gained. The law of conservation of mass means that...

How do you know whether to use any, no, or some? These determiners can be tricky in English but today we break down the rules so you can use them to make connections in English.

In this video Paul Andersen explains how chemical reactions progress as bonds are broken and reformed reformed. He explains the difference between changes in state and changes in molecules. He discussed collision theory and explains...

Matt attempts to get a bat out of the house.

This video is an educational program about physical and chemical changes in matter. The host uses examples such as baking cookies and a rusty bike fender to explain the concepts of physical properties of matter, chemical reactions,...
