latent heat of vaporization

A non-geology topic for a second.

We have been canning peaches this past week and as I was waiting and waiting for the canner water to start boiling I was thinking of a quick blog post. Canning is the culinary analog for splitting firewood. Lots of work in the fall leads to fresh peaches in February. All together we have about 40 jars of peaches. That sounds like a jar a week until next summer!

yes it was night by the time we had put enough energy in the system to change states from liquid to a gas.

Check out how much energy it takes to boil water compared to other materials. At a point in my ancient history, I was an operator in a coal fired power plant. That is when I first learned that much of the coal we burned was to put water over the edge from a liquid to a gas. (chart taken from wikipedia)
