Food and physics?!

cinderblock

I have to create a presentation on a physics-related topic. I personally love baking and would like to know what aspect of baking should I focus on that is also related to physics? Or how can i relate chocolate to physics?

Any help would be greatly appreciated!

Use a large chocolate candy bar and your microwave to determine the speed of light:

Why don't you look into the energy content per gram of a Snickers bar. See

http://caloriecount.about.com/calori...ers-bar-i19155

271 calories per 57 grams = 19,900 joules per gram. Now look up the energy content of gasoline (~44,000 joules peer gram). Both fuels get their energy from the heat of oxidation, in one case metabolism, and the other straight oxidation. How far can we drive a Prius on a Snickers bar?

As far as you can drive by lunchtime?

There are books about the connection of science to cooking.
I've only found the German link
http://www.amazon.com/Die-letzten-Ge...3712222&sr=8-2
But maybe you can google Peter Barham. He has given lectures in GB.

Also I have various articles from a German science magazine, so if you happen to know German let me know :)
