Answer:
Step-by-step explanation:
The changes that matter undergoes are associated with properties.
A physical change is one that alters the physical properties of matter. The physical properties of matter tells us everything about what a substance is when no change is occurring to its constituents. Such properties can be observed with our senses or instruments or pieces of apparatus. Examples are state of matter, colour, odour, taste, texture etc.
In many ways, physical changes are easily reversible and required little energy to initiate. There is no change in mass and no new kinds of matter are produced.
Examples of physical changes are boiling, melting, freezing, condensation, sublimation, magnetization of metals, breaking of glass, cutting of wood.
