The video is a lecture presentation discussing the consequences of osmosis. The presenter explains what osmosis is and how it works, with a focus on the movement of water molecules through partially permeable membranes. They also explain...

This is how a dipping bird toy/ drinking bird / dunking bird works explained. Explained with animations. A drinking bird works by cooling of the head via. evaporative cooling. That will cause the liquid (dichlormethane) inside the...

When you look through a straw in water something strange happens as you move it up and down.

Yes. Microwaves and radio waves are physically the same, i.e. both are forms of electromagnetic radiation. Some microwave rays can leak out and interfere with WiFi signals. We are basically constantly surrounded by electromagnetic...

This lesson will explain the differences between hydrated and anhydrous salts, including how to write their names and chemical formulae.<br/>
Definitions included: hydrated salt, water of crystallisation, anhydrous, anhydrate, aqueous salt

This video explains what transpiration is, how it can be estimated through experiments measuring the uptake of water by plants or the mass of water lost by the plants, and how changes in environmental conditions such as temperature,...

Let's journey deep into the cells themselves to take a look at some of the structures that keep cells alive and others that do... something... that we'll figure out someday... probably.

The video discusses the issue of ocean acidification and its impact on marine ecosystems and human health. It also highlights the work of scientists and organizations, including the XPRIZE Foundation, in developing tools to measure ocean...

Type II Alveolar Cells | Pulmonary Surfactant

The video is a tutorial on how to investigate temperature changes in chemical reactions, specifically focusing on the concepts of exothermic and endothermic reactions. The video explains the definition of the two terms and provides...

This video explains the process of transpiration in plants and how water is absorbed by specialized root hair cells. The video first defines transpiration as the loss of water from the surface of a plant and describes how leaves lose...

The video is a lecture presentation on the topic of osmosis experiment. The presenter defines osmosis as the diffusion of water molecules from a dilute solution to a concentrated solution through a partially permeable membrane. The...

This video explains how substances move in and out of cells via diffusion, which is the net movement of particles from an area of high concentration to an area of low concentration. The video first defines diffusion and illustrates it...

Superoxides and Superoxide Dismutase: Physiology, Biochemistry, and Inorganic Mechanism

The phrase “no two snowflakes are alike” is actually scientifically accurate. Snow forms high in the atmosphere, and despite its uniform appearance, each snowflake is different based upon where and how it was formed. Although snowflakes...

Dopachrome Tautomerase: Physiology, Biochemistry, and Mechanism

This video is the second of two lectures on osmosis experiments. The presenter discusses how to process and analyze the results obtained in the first presentation and estimate the sugar concentration in a potato cell. The presenter...

We know that redox reactions are ones that involve electron transfer. Something is oxidized, and something else is reduced. But these reactions can be tricky to balance when surrounding water molecules are involved in the reaction. Let's...

SOFIA Project Scientist Naseem Rangwala discusses the Stratospheric Observatory for Infrared Astronomy.

We've learned a lot about solution chemistry, and we've also learned about thermodynamics and spontaneity. So what about the spontaneity associated with dissolution? If an ionic solid dissolves in water, is this an enthalpically or...

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

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

This program covers the very important topic of hydrate compounds. We begin by discussing what a hydrate compound is and why they exist in nature. We discuss how to name hydrate compounds using numerous examples. The entire lesson is...

This is a lecture presentation on the electrolysis of aqueous solutions. The presenter explains what an aqueous solution is and what it contains, particularly aqueous solutions of metal salts. The presenter then presents a hypothesis on...
