What is the Meaning & Definition of physical change
A physical change is the concept that allows us to describe the transformation of matter characterized by not showing a variation in regards to the nature of the obligation. That is, in these types of changes there is a change in composition of the substance in question and therefore will not generate new substances while lasts the process. One of the main features of this type of phenomenon is the reversibility, situation that implies that vetilated change will not be permanent, then, then the substance experience a State and is transformed into another, immediately after may recover its original properties.
The most recurring ways that exist to detect these types of changes include, on the one hand, observation, from which detect the essential characteristics of an element using the senses as exclusionary tools. And on the other hand appears measurement, which is one of the most common methods that use science to investigate phenomena and which consists in the comparison of a sample with the object in question who has the physical quantity to be measured.
It should be noted that the changes of State are examples of physical changes.
Examples of this type of change the melting point and boiling point.
Boiling point is the temperature in which becomes matter from liquid to gaseous state, by putting it in simple terms, when water boils are to the boiling point.
And Furthermore, the melting point is that temperature in which becomes matter of the solid state to the liquid state, generating the same cast. Usually, this point is used to check the purity that some compounds.
