Khan Academy: Chemistry: Entropy Intuition
A video lecture to explain what entropy is and what it isn't. Two definition of entropy are introduced and explored to show how they can be reconciled. Also investigated is the second law of thermodynamics and its relationship to...
Khan Academy
Khan Academy: Thermodynamics: Thermo Can
This project demonstrates how to power a juice-can boat with a lighted candle. The candle heats the air, causing it to expand and push against the 'thermal sail' of the can, and move across the surface of the water. [3:53]
Crash Course
Crash Course History of Science #31: Marie Curie and Spooky Rays
It's time to talk about one of the most awesome scientists: Marie Curie. She figured out ways to get an education despite limitations of her homeland, was the first woman to win a Nobel Prize, and was the first person to win two Nobel...
Crash Course
Crash Course History of Science #26: Thermodynamics
It's time to heat things up! LITERALLY! It's time for Hank to talk about the history of Thermodynamics!!! It's messy and there are a lot of people who came up with some ideas that worked and others that didn't and then some ideas that...
