Vaporization is an example of an endothermic reaction. In chemistry, vaporization is defined as the transformation of a solid or liquid into gas. This is caused by either evaporation or boiling.Continue Reading
Exothermic and endothermic reactions both cause some type of energy level differences. In an exothermic reaction, energy is released in the form of heat. As chemical bonds are formed, energy is released. An example is water turning into ice. Chemical bonds form and release energy to create ice crystals.
An endothermic reaction, however, is the opposite. Here, the energy is absorbed in the form of heat. When a chemical bond is broken, the energy used creates an endothermic reaction. Changing ice into water, then vapor, requires the chemical bonds to be broken. That is why vaporization is an example of an endothermic reaction. Energy is used to break chemical bonds to cause the solid (ice) or liquid (water) to transform into vapor.
Other examples of an endothermic process are:
Some examples of endothermic reactions include:
An example of Gay-Lussac's Law in everyday life is the shooting of a gun. As gunpowder burns, it creates superheated gas, which forces the bullet out of the gun barrel following Gay-Lussac's Law. Other everyday life examples can be found in things that use gas and pressure in order to function.Full Answer >
An example of the law of conservation of mass is the combustion of a piece of paper to form ash, water vapor and carbon dioxide. In this process, the mass of the paper is not actually destroyed; instead, it is transformed into other forms. This best demonstrates the law that states matter cannot be created or destroyed. However, the form of matter can be changed.Full Answer >
The lowering of the vapor pressure of water due to the addition of solutes, such as acetone or ethanol, is an example of vapor pressure lowering. Vapor pressure is a colligative property of a solution that depends on solute concentration.Full Answer >
Ammonium nitrate dissolves in water with an endothermic reaction, a chemical reaction that consumes heat rather than releasing it. The temperature of the solution is lower than the starting temperature of either component chemical. Ammonium nitrate's solubility increases as the water temperature rises.Full Answer >
