When a substance changes its state, heat energy is involved. This energy is used not to heat up the substance, but to separate the molecules from each other. This is known as specific latent heat. Specific latent heat is defined as the...

You might have noticed that if you are trying to boil a lot of water it takes longer than if you only wish to boil a small amount of water. This is all because of something called ‘heat capacity’. Keep watching to learn more. Before we...

SciShow News explains the latest climate weirdness, and why the Global Warming Hiatus wasn’t really what it sounded like. Plus, see how humans have harnessed the climbing power of the gecko!

If you have ever torn up a piece of paper or seen ice melt, then you have witnessed physical changes. This fascinating program helps students understand some of the different ways matter changes physically. Vivid animations also...

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...

Tornadoes are the most violent storms on Earth, with wind velocities that can exceed 200 miles per hour. How do these terrifying cyclones form? Meteorologist James Spann sheds light on the lifespan of tornadoes as they go from supercell...

Most people are taught that dinosaurs went extinct 66 million years ago when a giant meteor crashed into the Yucatan peninsula. I'm here to tell you that's wrong. Dinosaurs are alive and well today, and you don't have to go to Jurassic...

The malaria vaccine was invented more than a century ago -- yet each year, hundreds of thousands of people still die from the disease. How can we improve this vital vaccine? In this informative talk, immunologist and TED Fellow Faith...

David Thouless, Duncan Haldane, and Michael Kosterlitz won the Nobel Prize in Physics in 2016 for discovering that even microscopic matter at the smallest scale can exhibit macroscopic properties and phases that are topological. But -...

This video is a lesson on the physical changes that occur in matter as its internal energy increases. The video describes how the physical state of matter changes as it is heated, from a solid with particles in fixed positions to a...

University of Pennsylvania physicist Justin Khoury describes how, while many are convinced of the existence of dark matter rather than changing our understanding of the laws of gravity, we can’t yet be sure what the final outcome will be.

This video is a lecture on specific latent heat, which looks at the energy absorbed or emitted by a substance as it changes states (solid, liquid, or gas). The lecture discusses two equations that can be used to calculate the amount of...

Upon viewing the The Changing Phases of Matter video series, students will be able to do the following: Explain that phases of matter, also called states of matter, are the physical forms matter can take. State the four phases of...

Learn all about the states of matter - solid, liquid and gas. We explain the concepts of freezing, melting, evaporation, and condensation, and discuss the reversibility of physical changes. We also distinguish between physical and...
