This easy to understand video is all about properties of matter.
Properties of Matter
Matter is anything that takes up space and composed of miniscule particles called atoms. It must display the two properties of mass and volume.
The different types of matter can be differentiated through two components: composition and properties. The composition of matter mentions the different components of matter along with their relative proportions. The property of matter means the attributes that differentiate one sample of matter from another. These properties are of two types: – Physical and Chemical
Physical properties: –
If we are measuring a physical property then we do not need to change the composition of matter. These properties are used to measure and describe matter. Two types of physical properties are there:-
Intensive Property: – A physical property that will not be changed if the amount of matter changes such as density and colour.
Extensive Property: – A physical property that will not remain the same if the amount of matter changes such as mass and volume.
Physical change: –
A physical change will take place without any requirement of changing molecular composition. The same element is present before and after the change. The same molecule will be present throughout the changes. These changes are related to physical properties since some measurements require that changes be made.
Chemical Properties: –
Chemical properties show the potential of matter to go through some chemical changes or reaction. It will change the molecular composition of the element as well. It is quite difficult to define a chemical property without using the word change.
Chemical changes: –
Chemical change results in one or more substances which have a completely different composition from the original elements. The elements and compounds at the start of the reaction are rearranged into new elements. Or we can say, chemical change alters the composition of the original matter.
