Free Energy of Dissolution
We've learned a lot about solution chemistry, and we've also learned about thermodynamics and spontaneity. So what about the spontaneity associated with dissolution? If an ionic solid dissolves in water, is this an enthalpically or...

How Brownian Motion Helped Prove the Existence of Atoms
We’re going to see a type of motion over and over again because it’s all over the microcosmos, found in and around many different types of organisms. And this kind of random motion may seem almost too trivial to discuss, but this motion...

Water and Diffusion - The Chemistry of Life
In this section, I talk about the properties of water, and what makes it unique. I talk about hydrogen bonds that result from the polar nature of water and why ice floats.
I also deal with diffusion and go into the 3 factors that affect...

Temperature and Gas Solubility
We know about solutions and solubility, but we have typically examined solid or liquid solutes dissolved in a liquid solvent. Did you know that gases can also be dissolved in liquids? Their solubilities depend heavily on temperature, so...

Xylem and Phloem - Part 2 - Transpiration - Transport in Plants
Transpiration is the evaporation of water from the aerial parts of a plant (so the leaves and stems). By water evaporating out of these parts - mostly the leaves, a suction pressure is created which draws water up through the plant. This...
