An endothermic reaction is one in which heat flows from the system to the surrounding‚ which is the process of absorbing heat. Heat flowing into a system from its surroundings is defined as positive; q has a positive value. An exothermic reaction is when heat flows from the surroundings into the system‚ which is the process of releasing heat. The heat flowing out of a system into its surroundings is defined as negative; q has a negative value because the system is losing heat. Endothermic reaction:

Exothermic and Endothermic Reactions The release of energy in chemical reactions occurs when the reactants have higher chemical energy than the products. The chemical energy in a substance is a type of potential energy stored within the substance. This stored chemical potential energy is the heat content or enthalpy of the substance. The collection of substances that is involved in a chemical reaction is referred to as a system and anything else around it is called the surroundings. If the enthalpy

Marco Grogan‚ Emily Hendrigan Group 6‚ period 5 10-05-17 A cold pack is a device that creates an endothermic reaction by mixing water and one of many possible chemicals. In the scientists’ experiment they will find out which chemical will keep the water cold the longest. The independent variable for the experiment is the amount of chemicals (in teaspoons) added to each cup of water‚ while the dependent variable is the temperature of the water before and after the experiment‚ and the constant
