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.

We learned about ideal gases and the ideal gas laws, and we briefly touched on kinetic molecular theory, which puts these laws in context. But let's now go through this theory more rigorously, analyzing each postulate one at a time.

Soil is a vital natural resource that supports life on Earth. It is a mixture of minerals, organic matter, gases, liquids, and organisms. Soil plays a crucial role in providing nutrients and moisture for plant growth, purifying water,...

This video lecture focuses on how the volume of a gas affects its pressure. It first explains how temperature affects pressure and then delves into the example of how a fixed mass and temperature of gas stored in a piston react to...

Learn the basics about Diffusion of gases. How are gases diffused? What methods are used to diffuse gases? Find out more in this video!

This video provides a concise explanation of what fire is, how it is formed through a chemical reaction, and its various uses and effects. It highlights the importance of fire for survival, its historical significance, and how it can be...

The discovery that passing an electric current through water would split it apart was made quite soon after the discovery of current electricity itself. This predates Michael Faraday’s work in this area, but it is he who introduced most...

Learn the basics about changes of state as part of the solids, liquids and gases topic within properties of matter.

It explains area expansion, volume expansion, constants of proportionality and relation between coefficient of linear expansion and volume expansion with examples.

Upon viewing the Forces in Fluids video series, students will be able to do the following: Define fluids as substances that can easily flow and readily change shape. Explain that fluids flow because particles can easily move past each...

This animated video is all about The Sun. Students will love this engaging and interactive video.

How do Vacuum Pumps work. Vacuum Pumps Explained. In this video we learn how vacuum pumps work, the main parts of a vacuum pump and where we use them. This covered the basic working principle of single stage and two stage vacuum pumps...

Water commonly exists in three different forms: ice, liquid water, and water vapor. In this video the different phases of water serve as the foundation to teach about solids, liquids, and gases. Other common everyday examples of solids,...

This video explores five fun facts about Climate Change

This video discusses the properties and characteristics of the noble gases, which are situated on the far right of the periodic table. The video explains how their unreactive nature leads them to exist as single atoms, which is different...

In this video, we learn about the element neon and its significance in the periodic table. Despite its classification in the "sad" group of the periodic table, neon holds great value. The video highlights its use in electric lights,...

In this video, the topic of discussion is hydrogen, the first element in the periodic table. The video highlights the importance of hydrogen in chemistry and its abundance in the universe. The video also mentions the industrial uses of...

Oxygen is the chemical element with the symbol O and atomic number 8. Oxygen is a necessary and abundant resource on Earth. Learn about the many things oxygen is used for - including keeping humans alive!

Real World Science : The Science of Climate Change
<
br/>
This program begins by explaining how scientists have learned that Earth’s climate has changed many times over billions of years and that Earth’s climate is...

It explains the behaviour of real gases and their deviation from ideal gas behaviour(compressibility factor) It derives van der Waal's equation for real gases.

Respiration is carried out by all living things. Animals need oxygen to carry out aerobic respiration and they need to get rid of the waste product called carbon dioxide. This is called gas exchange. Swapping one gas for another. Animals...

The video explains the importance of breathing for all animals, including humans, and the process of cellular respiration that requires the exchange of gases between the organism and the environment. Respiration part 2/10

Learn the basics about climate change and how burning fossil fuels adds extra carbon dioxide to the atmosphere, and how this then leads to climate change. Fossil fuels, like oil, coal and natural gas, are the remains of living things...

In this video, we discuss the following:<br/>
[1] what is a partia<br/>l pressure?
[2] the basics of Dalton's la<br/>w of partial pressures
[3] how these relate to atmospheric gas that we breathe
