Comorbidities are two or more diseases existing at the same time in the body. They are common for people with COPD because organ systems work differently when they do not receive enough oxygen. When a resulting condition occurs, it can be considered comorbidity.
1 Viscosity is another type of bulk property defined as a liquidâs resistance to flow. When the intermolecular forces of attraction are strong within a liquid, there is a larger viscosity. 2  Viscosity can be not only a fluidâs resistance to flow but also a gasâ resistance to flow, change shape or movement. The opposite of viscosity is fluidity which measures the ease of flow while liquids such as motor oil or honey which are âsluggishâ and high in viscosity are known as viscous.
