1. A food sample is burned in a calorimeter that contains 2000. g of water. The temperature increases from 22.0°C to 44.3 °C. How many Calories does the food sample contain, assuming all of the energy from the food was transferred into the water?

Why doesn't water light on fire? It has all the ingredients except heat! Hydrogen for the flammability factor, oxygen so it can keep burning, and all you need to do is add heat and BOOM you have a flame! 15 pts
