Notes
Points to note
- In daily life, we encounter different substances also called matter. The air we breathe, the water we drink and soil are all forms of matter. Matter is anything that has mass and occupies space. Matter exists in three states namely; solid, liquid and gas (vapour/air).
- The three states of matter can be changed from one state to another as shown in Figure 1.
- Matter can be changed from one state to another by, heating or cooling. Pressure changes can also have the same effect on the states of matter.
