Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ventures too close鈥攂e it star, planet, or spacecraft鈥攚ill be stretched and compressed like putty in a theoretical process aptly known as spaghettification.

What is the Zeroth Law of Thermodynamics?

Why is there a zeroth law of thermodynamics? What use is such a simple-sounding law? And how can it be used to smash glass? Chemical engineer Valeska Ting explains in the first film from our 2016 advent calendar, all about thermodynamics.

The first, second and third laws of thermodynamics get all the glory. They鈥檙e the most well known and frequently mentioned. But underpinning them all is a final law so fundamental that, although it was established last, had to be moved to the front of the list: the zeroth law. In the first film of our 2016 advent calendar, chemical engineer Valeska Ting explores the zeroth law of thermodynamics.

The zeroth law is essentially an observation: if two systems are both in thermal equilibrium with a third, they are also in equilibrium with each other. This seemingly simple mantra is essential to our concept of temperature, as Valeska, armed with some very hot glasses, explains.

Our 2016 advent calendar explores the four laws of thermodynamics through 24 short films, released daily in the run up to Christmas. We鈥檒l have explosive demonstrations, unique animations and even a musical number. Sign up to receive each instalment by email from rigb.org/advent

Understanding Second Law of Thermodynamics !

tutorsmediavideos
1 Views 5 months ago

The 鈥楽econd Law of Thermodynamics鈥 is a fundamental law of nature, unarguably one of the most valuable discoveries of mankind; however this law is slightly confusing for most engineers or students. The main reason for this is because it has so many complex terms in it and that there are many ways that this second law can be stated, but most importantly, the majority do not understand what are the applications of this law. In this video we will create a real physical insight into this law with a minimum use of mathematics.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

The First & Zeroth Laws of Thermodynamics: Crash Course Engineering #9
00:10:05
tutorsmediavideos
11 Views 5 months ago

In today鈥檚 episode we鈥檒l explore thermodynamics and some of the ways it shows up in our daily lives. We鈥檒l learn the zeroth law of thermodynamics, what it means to reach a thermal equilibrium, and define the first law of thermodynamics. We鈥檒l also explore how stationary, adiabatic, and isochoric processes can make our lives as engineers a little easier.

Note: Different branches of engineering sometimes define the first law of thermodynamics differently, depending on how work is defined. Essentially, work released from a system might be defined as a positive value or a negative value, and thus the first law can be defined as either Q-W or Q+W. Both are acceptable forms, depending on how the system is defined! We chose to focus on only one definition here to limit the confusion.

First Law of Thermodynamics, Basic Introduction - Internal Energy, Heat and Work - Chemistry

This chemistry video tutorial provides a basic introduction into the first law of thermodynamics. It shows the relationship between internal energy, heat, and work. It discusses the difference between the system and surroundings and distinguishes an open system from a closed system and an isolated system. In chemistry, work is positive whenever work is done on the system and work is negative whenever work is done by the system. During an exothermic process, heat flows out of the system and it flows into the system during an endothermic process.

Have you ever heard of a Perpetual Motion Machine? More to the point, have you ever heard of why Perpetual Motion Machines are impossible? One of the reasons is because of the first law of thermodynamics! In this episode of Crash Course Physics, Shini talks to us about Thermodynamics and Entropy. Also, we learn about Isovolumetric, Isobaric, Isothermal, and Adiabatic processes. It'll all make sense in a minute!

This video features experiments that have been shown to me by science teachers over the years. Does ice melt fast in salt water or fresh water was an experiment introduced to me at the Utah Science Teachers' conference. The ring of metal over a chain demo came from a teachers event in Florida. The idea shaking a carbonated drink increases pressure came from an email.

Special thanks to Petr Lebedev for building the pressure gauge.
