Osmoregulation
Paul Andersen explains how organisms regulate their internal osmolarity or not. He starts with a brief description of osmosis and why it is important for animal cell to be surrounded by an isotonic solution. He then explains how...

Ideal Gas Problems: Crash Course Chemistry
We don't live in a perfect world, and neither do gases - it would be great if their particles always fulfilled the assumptions of the ideal gas law, and we could use PV=nRT to get the right answer every time. Unfortunately, the ideal gas...

5 Inventions Showing Us the Future of Solar Energy
When you imagine the energy of the future, solar power is probably in the picture – but in recent years, less than 2% of the world’s electricity has come from solar power. Here are 5 new inventions that are likely to change that.

What Happens When You Get Electrocuted?
Most of the cases we call “electrocutions” are actually electric shocks: an electric current running through a body. Whether an electric shock becomes an electrocution depends on the nature of the current involved.

Enthalpy of Reaction
In this video Paul Andersen explains how the enthalpy of a reaction can be released in an exothermic or consumed in an endothermic reaction. According to Hess's law if the reaction is reversed the sign of the enthalpy of reaction is...
