GENERIC NAME: enalapril. DRUG CLASS AND MECHANISM: Enalapril is a drug that is used for treating high blood pressure. It is in a class of drugs called angiotensin converting enzyme (ACE) inhibitors. ACE is an enzyme in the body that causes the formation of angiotensin II.
RECOMMENDED LESSONS: Chemical energy. Chemical Energy is energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by product (exothermic reaction) . Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy.
In an inverse way heat leaves a gas to change the molecular bonding when the gas condenses into a liquid, and heat leaves a liquid to change the molecular bonding when it freezes into a solid. In none of these changes of state is the heat (energy) that is input or output used to change the speed of the molecules. The average speed of the molecules is the same before and after a phase change, and so is the average kinetic energy.
