Understanding Pressure in Chemistry

Understanding Pressure in ChemistryScience and engineering students in this field should understand the principles of pressure in chemistry, as well as its influence in all areas of life. A great deal of stress can be exerted by even the most insignificant pressures on humans. Stress is a physical reaction that arises from excessive demands made upon the body. This stress can range from simple everyday tension to serious health complications.Pressure in chemistry relates to the nature of substances in the molecules of matter. Chemists do not restrict their study to just the substances found in the atmosphere, but look at the properties of all elements within the earth's crust. The properties of molecules depend upon the substances that compose them. Thus, it is important for students of chemistry to understand how pressure in chemistry affects all materials.The primary purpose of the element in molecules is to transfer pressure and is known as chemical stress. The function of an elem ent is defined by its chemical potential. The constant pressure exerted upon a substance by a simple molecule will cause the molecule to undergo a change in atomic structure.Elements that contain more than one hydrogen atom are said to have more than one chemical potential. Hydrogen is a unique molecule because it has two molecular bonds instead of one. This makes it easier for the chemical changes to occur.Stress in chemistry is similar to stress in the other sciences. It can arise when one material causes a force upon another. Examples of stress in chemistry include colloids (liquid) and solids (solid).Pressure in chemistry can affect a solid or a liquid depending upon the structure of each material. The composition of a compound will influence the pressure exerted upon it by the other material. For example, in water, a drop of water will rise if a lump of ice, or a container filled with water, is placed under it.When a drop of water is pressed down upon the ice, water expands. Th is causes the ice to move upward and leave the container, causing the ice to freeze. The same thing occurs when a lump of water is put under a drop of water.
