## Properties of Matter in Physics

Properties of Matter in Physics: The physical quality is a quality of a substance that can be seen or changed. Physical properties include a wide array, which can be classified as deep or broad.

Physical properties of matter

• The mass
• Volume
• Density
• Specific gravity

## Mass

Mass is the basic property of an object and it opposes the acceleration of that substance. The mass of an object is known only by its weight. If an object is heavy, its mass will also be greater. Therefore, we get to know the weight of matter and the strength of gravity by mass. Mass depends entirely on the volume of the substance. The SI unit of mass is the kilogram.

## Volume

```The amount of matter that surrounds it is called the volume of that substance. To find the volume of a substance, it is necessary to know the length, width and height of that substance.
```

## Density

The mass contained in the unit volume of a substance is called the density of that substance. Hence density is a measure of the density of a substance. Its unit is kg per cubic meter.

## Specific gravity

The specific gravity of an object is derived by dividing its density by the density of a ‘reference substance’. Often the density of other substances is expressed relative to the density of water.

### Properties of Matter in Physics

include size, shape, color, texture, etc. The melting point and freezing point also are physical properties. Every substance has some physical properties that are different from those of other substances (how is wood different than metal or plastic?). Physical properties are often changed, sometimes permanently and sometimes irreversibly. for instance, when the ice melts the water can then be refrozen but when the wood is burned many of its atoms leave as gas (carbon dioxide and water vapor), and therefore the match can’t be replaced together to its original state.
