![]() A lot of them function by "cracking" (or bending) them. Heating packs (used to warm up cold hands or soothe sore muscles) have chemicals inside them. ![]() The stomach (and small intestine) then release that glucose into the bloodstream, serving as energy for our bodies. This process turns carbohydrates into glucose. Our bodies digest food by mixing it with acids and enzymes in the stomach. Food: chemical energy in food is released when the food is digested and the molecules of food are broken down into smaller pieces.Two units of solid TNT can instantly change into 15 units of hot gas, creating a dark and sooty explosion. But, when a solid material quickly changes into a hot, expanding gas, you may be looking at an explosion. Just because chemical energy is being released, it doesn't mean an explosion will occur. Explosives: when an explosive goes off, chemical energy that was stored in it is changed and transferred into sound energy, kinetic energy, and thermal energy.Of course, you can't see the energy in the battery when the battery is just sitting around it is when the electricity is produced that the energy is seen. When something's connected to a battery, chemical reactions take place along the electrodes to produce electricity. They're separated by an electrolyte, a chemical that allows the anode and cathode to transmit a charge. Batteries have two terminals: the anode and the cathode.This chemical reaction is safe, making it a great science activity for kids. As this gas grows in volume, it puts pressure on whatever container it is in, and will erupt out of an opening in the container, creating a volcano effect. ![]()
