There's No Such Thing As Cold
You've felt cold before. Sometimes it's cold outside. But what if I told you that "cold" isn't real? There's no substance or quantity called "cold" in science. We can't measure the amount of "cold" in something. Instead it's about what's...

Intermolecular Forces and Boiling Points
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!

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...

The End of the Universe: Hot or Cold?
We've talked at great length about the beginning of the universe, everything we know, and what we don't yet know. But everything that has a beginning must have an end. How will the universe end? How can we tell? When will it happen?...

Converting Between Temperature Scales (Celsius, Fahrenheit, and Kelvin)
If you're American, you're familiar with the Fahrenheit scale, so 30 degrees is cold and 100 degrees is hot. But in the rest of the world, nobody uses this scale! They use Celsius, and to them, 30 is pretty darn hot. Furthermore,...
