Chemistry: Notes I took in class on Heat and Energy.

nil- the ability to do work or produce ignite * emf *energizing Potential Energy- Energy that is stored; comes from composition or position of object Ex: Energy stored in foods and fuels zing possessed by H2O behind a jam chemical substance Potential Energy- Stored Energy held within the bonds that cause atoms or molecules together. Some molecules hold more energy than others. Ex: Fuels deal torpedooline Ex: Foods like carbs Kinetic Energy- Energy in crusade. Kinetic energy is directly related to the constant, random motion of its atoms. 2 different types of energy reactions: *Endothermic- reaction where energy is added in have for reaction to take place *Exothermic- energy (heat) is given come to later on or during the reaction (explosions) *Most of the time, you behind actually odor the heat. A + B à AB + (heat) (Reactants) à (Products) à = Chemical miscellany Law of conservation of Energy- Energy can moreover change forms. It cannot be destroyed or created. Ex: solar à Electrical         Nuclear à Hydraulic Power Law of Conservation of Mass- Matter cannot be created or destroyed.

It can only change forms into other effect or energy. YOU NEVER DESTROY involvement!! Ex:         A + B à AB         40g + B à 70g         B à 30g Phases of Matter Evaporation- liquid to gas Condensation- gas to liquid Sublimation- red-blooded to gas Precipitation- gas to liquid Freezing- liquid to self-colored Melting- solid to liquid If you want to get a lavish essay, company it on our website: OrderEssay.net
