RESULTS Energy Content Energy change = mass x specific heat capacity x change in temperature Bread = 50x4200x2.5= 525J Almonds =50x4200x33= 6930J Beans =50x4200x8= 1630J Peanuts =50x4200x25= 1680J Butter =50x4200x9= 1890J Margarine =50x4200x7= 1420J OBSERVATIONS * The food substances that had oils (nuts) contained the most energy * Almonds contained the most energy (6930 1) * The lipids contained more energy than the proteins and the carbohydrates. Bread had 525J, while beans had 1630 J.
