In combat zones, soldiers eat packaged food called “Meals Ready to Eat,” or MREs. Soldiers must cook the package contents for several minutes without the use of fire or electricity. A chemical warming packet is included as part of the MRE. When the soldier adds water to the chemical warming packet, a reaction occurs that warms the food in the MRE. -Using the warming of food in an MRE as a model, explain the general behavior of any chemical system that involves a warming effect. Include the terms process, output, and energy flow in your explanation.
-Describe any energy transformations that occur within the MRE system.
