Pumps are devices used to move liquids or slurries. Liquids are moved from higher pressure to lower pressure, and overcome this pressure by adding energy to a system. Pumps can be classified as either being positive...

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 video, students learn how to find the volume of liquids by using different measuring tools, specifically graduated cylinders. They are introduced to the common units of liquid volume measurement, milliliters (mL) and liters (L),...

This short video explains how a raindrop falls through the atmosphere and why a more accurate look at raindrops can improve estimates of global precipitation.

In this video, we will discuss a heating and cooling VRF system. This system allows buildings to provide heating and cooling from the same system.

We know that the free energy change associated with a process will tell us whether it is spontaneous or not. And we also know that this depends on the change in enthalpy and the change in entropy for that process, as well as the...

The video discusses the concept of convection as a mechanism of thermal energy transfer in fluids. It explains how convection currents are formed due to temperature differences and particle movement in liquids and gases. The video also...

Earth's climate system has been remarkably stable over the last 20,000 years or so. Human civilization developed in that time span, and our world's average temperature warmed by about 5 degrees C to the temperature it is today. This...

Liquid cooling isn’t just for enthusiasts. It is quieter and much more efficient than traditional air cooling. Today’s liquid cooling solutions are easy to use and interface with any system. This clip is from the chapter "CPUs" of the...

We just learned two separation techniques, so let's learn one more! Distillation separates compounds by virtue of their differing boiling points. If two liquids are miscible, we can't perform extraction, but if they have very different...

An air conditioner is a machine that cools a large space such as a house or a building. Examine the three main parts of an air conditioner - the compressor, condenser, and evaporator - and learn how they create and circulate cold air?

Life as we know it requires three ingredients: energy, organic...

This lesson will give you useful airport English words and phrases you can use at the airport. When’s the last time you flew somewhere? Did it go smoothly, or was it stressful?

For your next flight, let’s make sure you...

In the video, the lecturer discusses the differences between wealth and income, and introduces the concepts of liquidity, stock, and flow. The video includes charts and surveys to illustrate the points and concludes by highlighting the...

Cheese is a dairy product made by coagulating ceisin in milk to separate it from the whey. Learn more about the dairy product and how to make your own cheese!

We are just about ready to do some interesting experiments, but first we need to learn about a very important instrument, pipettes. These are used to transfer specific amounts of liquid from one vessel to another, and there are many...

Although kidneys are clearly important for survival, they are not essential, and this is particularly true if only one kidney is present. Some people are born without one of their kidneys, a condition called renal agenesis. Some other...

Marisa McClellan, of Food In Jars, shows us how to can marinated red peppers. These red peppers are great in sandwiches, salads, or in an antipasto plate.

We were lucky enough to get early access to THE WORLD'S LARGEST INDOOR TROPICAL RAINFOREST at The Eden Project. Whilst playing on the awesome cloud bridge we thought what better question to tackle than...How do Rainforests Make...
