The unique force created by hydrogen bonding gives water some unique properties, which seem to defy the laws of nature. Chemistry - Atoms And Bonding - Learning Points. Hydrogen bonding is a special force of attraction between water...

A blizzard creates a blanket of snow. Look closer and the true beauty of individual snowflakes can be seen. How are different shapes of snowflakes formed and why are they always perfectly symmetrical? Chemistry - Atoms And Bonding -...

The difference between air-drying and tumble-drying is that air-drying keeps the cellulose fibers from reforming their hydrogen bonds more effectively, which makes the towel feel a bit fluffy. Tumble drying, on the other hand, causes the...

Water evaporates at room temperature because the molecules at the top of the liquid have less intermolecular attraction than those within the bulk. When the top layer is exposed to sunlight, some molecules gain enough kinetic energy to...

Explore the science of washing different types of clothes. Understand why wool shrinks in hot water, how cotton behaves differently, and the importance of washing at various temperatures. Learn tips to prevent color bleeding and...

This explains structure and properties of water including hardness of water and methods of removing the hardness.

It explains the preparation of Ammonia from ammonium salts & by Haber's process as well as explains the physical , chemical properties & uses of Ammonia.

Why do different liquids boil at different temperatures? It has to do with how strongly the molecules interact with each other. Find out all the different ways, and how to use them to make predictions about matter!

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

This program begins by defining heat of vaporization is the amount of heat that must be added or given off to vaporize one gram or kilogram of a substance and is expressed as J/g or J/kg. Through real, live footage and animation,...

In this section, I talk about the properties of water, and what makes it unique. I talk about hydrogen bonds that result from the polar nature of water and why ice floats.



I also deal with diffusion and go into the 3 factors...

This nugget describes historical aspect of discovery of nucleic acid, basic structure of polynucleotide chain, Watson model of DNA and types of DNA.

It describes the mechanism of ascent of sap by the theories of root pressure and transpirational pull. It explains the cohesion-tension-transpiration pull model of water transport.

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

The science that makes ice slippery also makes the Olympic Winter Games possible. But exactly what makes ice slippery? Ken Golden, a mathematician at the University of Utah, explains how the unique surface of ice makes the slide and...

Learn what intermolecular forces are, the three most common types and the differences between them. An intermolecular force is simply an attractive force between neighbouring molecules. There are three common types of intermolecular...

Liquids have some very interesting properties, by virtue of the intermolecular forces they make, both between molecules of the liquid and those between the liquid and some other material they are in contact with. Let's learn about...
