Food and physics?

  1. May 12, 2010 #1
    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/calories-snickers-bar-i19155 [Broken]

    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?
