It explains solution and its properties. It also talks about the concentration of a solution.

The video explains the concept of density, which is the mass of a substance in one cubic meter of it. The equation for calculating density is explained as well as illustrated with a simple example, where a glass block is weighed to find...

This nugget explains about rotational equivalents of mass and energy ,it describes the radius of gyration.

A Level Physics - Doodle Science teaches you GCSE and A Level physics in a less boring way in almost no time!

In this video, the teacher explains how to determine the shape of a cross section when slicing a three-dimensional solid. By analyzing whether the slicing plane intersects with straight or curved surfaces, students can visualize and...

In this video, a teacher explains how to graph linear inequalities in two variables and use them to solve real-life problems. The teacher covers topics such as the solution set, boundary lines, test points, and determining solutions. The...

Learn the basics about Behaviour of metallic structures. How many types of metallic structure do you know? and what are their purposes? Find out more in this video!

In this video lesson we will learn how to identify vertices, edges and faces on a three-dimensional solid. We will learn that the edges meet at the vertices. We will discover that each face is formed by edges. We will discover the...

This live-action video program is about the word freezing. The program is designed to reinforce and support a student's comprehension and retention of the word freezing through the use of video footage, photographs, diagrams, and...

What happens when you pour liquid nitrogen on a flame? What about when you blow on the flame with a cup in the way? Try these five unusual ways to extinguish a candle. Pour out the flame with CO2. Cut off the oxygen supply to the flame...

Glass is made by heating sand (mostly composed of silicon dioxide) until it melts and turns into a liquid at a high temperature of around 1700° Celsius. When the molten sand is allowed to cool, it becomes an amorphous solid, featuring...

Now that we have covered some important separation techniques, let's take a look at a purification technique. Sometimes a chemical reaction will produce a solid, which can precipitate from solution. But these crystals typically contain...

The video provides an explanation about the structure and behavior of ionic compounds. It discusses how positively and negatively charged ions are attracted to each other and arrange themselves in a giant lattice structure to maximize...

The three dimensions that form a solid are: length, width, and height.

In this video, the teacher explains how to find the volume of an irregular 3D solid by recognizing that volume is additive. They demonstrate this concept by breaking down the solid into two rectangular prisms and finding the volume of each.

How to find the volume of a solid of revolution by the method of cylindrical shells.

We've learned that some ionic solids are totally water insoluble, but in fact this is a slight oversimplification. Even such solids will dissolve to some minuscule degree, and we can measure this, and do calculations with it. Let's learn...

What are the unique properties of water? What are the freezing and boiling points of water? Properties Of Water, Part 2

NASA's Hubble Space Telescope observed the farthest-discovered active inbound comet, Comet K2. K2 came from the distant Oort Cloud and is visiting our inner solar system for the first (and only) time. Since we're seeing it so far...

It defines the term reaction enthalpy,expression for the enthalpy change, standard enthalpy of reactions and formation as well enthalpy change during phase transformations.

This lecture video explains how sound waves propagate, transfer from air to a solid, and how the human ear works. The video then explains how sound waves interact with solids, including reflection, absorption, and transmission. The video...

Prof Hal Sosabowski demonstrates this simple yet effective experiment, which reveals several properties of solid carbon dioxide. Hal shows us how clouds of water vapour can be formed, how carbon dioxide is denser than air, how a gas...

Why do some things dissolve in water while others don't? Is a supersaturated solution just a beaker with a cape? All this and more!

Upon viewing the What is Sound video series, students will be able to do the following: Understand that sound is produced when matter vibrates. Explain that sound energy can travel through air, liquids, and solids, which are generally...
