The Impossibility of Perpetual Motion Machines
Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the perpetual motion machine. No working perpetual motion machine has ever been experiment verified. All break the laws of...

Spontaneous Processes
In this video Paul Andersen discriminates between spontaneous (or thermodynamically favored) processes and those that are not spontaneous. A spontaneous process requires no external energy source. If the enthalpy change in a reaction is...

TED-ED: What triggers a chemical reaction? - Kareem Jarrah
Chemicals are in everything we see, and the reactions between them can look like anything from rust on a spoon to an explosion on your stovetop. But why do these reactions happen in the first place? Kareem Jarrah answers this question by...

Thermodynamics: Crash Course Physics
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...

Is ACTION The Most Fundamental Property in Physics?
It’s about time we discussed an obscure concept in physics that may be more fundamental than energy and entropy and perhaps time itself. That’s right - the time has come for Action.

Enthalpy: Crash Course Chemistry
Energy is like the bestest best friend ever and yet, most of the time we take it for granted. Hank feels bad for our friend and wants us to learn more about it so that we can understand what it's trying to tell us - like that any bond...

Spontaneity
It explains the transfer of heat from colder to warmer bodies, relation between entropy and spontaneity,Gibbs energy and spontaneity.

How We Use the Sun
Theoretical physicist and Nobel Laureate Roger Penrose (Oxford) describes how the sun's entropy is harnessed by all manner of life on earth.

The Third Law of Thermodynamics: Absolute Zero
Brr, it's so cold today! Could it get any colder? Is there a coldest possible temperature? Yes, there is! That seems strange, but now we know that temperature is just a measure of kinetic energy, so zero kinetic energy must mean zero...

Solubility and the Born-Haber Cycle
Why do some things dissolve in water while others don't? Is a supersaturated solution just a beaker with a cape? All this and more!

TED-Ed: The chemistry of cold packs - John Pollard
If you stick water in the freezer, it will take a few hours to freeze into ice. How is it, then, that cold packs go from room temperature to near freezing in mere seconds? John Pollard details the chemistry of the cold pack, shedding...

Sean Carroll: Distant time and the hint of a multiverse
Cosmologist Sean Carroll attacks -- in an entertaining and thought-provoking tour through the nature of time and the universe -- a deceptively simple question: Why does time exist at all? The potential answers point to a surprising view...

The Arrow of Time and How to Reverse It
Ever wish you could travel backward in time and do things differently? Good news: the laws of physics seem to say traveling backward in time is the same as traveling forwards. So why do we seem to be stuck in this inexorable flow towards...

The Physics of Life (ft. It's Okay to be Smart & PBS Eons!)
Our universe is prone to increasing disorder and chaos. So how did it generate the extreme complexity we see in life? Actually, the laws of physics themselves may demand it.

Why Do You Remember The Past But Not The Future?
The laws of physics don’t specify an arrow of time - they don’t distinguish the past from the future. The equations we use to describe how things evolve forward in time also perfectly describe their evolution backwards in time. So the...

What Happens After the Universe Ends?
Conformal Cyclic Cosmology is a story of the origin and the end of our universe from great mathematical physicist Sir Roger Penrose. It’s goes like this: the infinitely far future, when the universe has expanded exponentially to to an...

Can We Reach Absolute Zero?
Absolute zero is the temperature at which entropy reaches its minimum value, and all energy has been taken out of a system. But is it reachable? Can anything ever be that cold? Nobel Prize-winning physicist William Phillips explains the...
