Discussion
Chemistry is the study of matter. It is very common for a pill roller to need to describe a bit of matter as thoroughly as possible. In doing so, the chemist would certainly amount physical properties.
Many physical properties can be spy using our senses; color, crystal shape, and phase at room temperature are some examples. Other physical properties involve quantitative observations and so must be measured; density, specific heat capacity, and boiling point are three examples. A physical change is any change in a substance that does not involve a change in its chemical composition. During a physical change, no new chemical bonds are formed, and so the chemical composition remains the same. Examples of physical change are boiling, freezing, expanding, and dissolving.
Matter can also be characterized by its chemical properties. The chemical properties of a substance include all the chemical changes possible for that substance. A chemical change is one in which the substance is transformed to a new substance. That is, there is a change in the...If you want to get a integral essay, order it on our website: Orderessay
