**COMMON PROPERTIES OF SUBSTANCES,**

**1. Inertia 2. Volume 3. Masses**

1. Inertia the tendency of a substance to maintain its state of motion and shape is called inertia. A passenger who wants to get out of the car is forced to go in the direction of the car’s movement if the car gets off before it stops. A passenger with a speed while in the car will want to continue this speed when they land. This applies to all substances. A standing substance wants to stop, and if it is in motion, it wants to continue its movement.

2. Volume is the volume of a substance. Two substances cannot occupy the same volume together. For example, when water is placed in a cup, the air inside the Cup leaves the cup.

3. Solids have a certain shape and volume. Although liquid substances have a certain volume, they do not have a certain shape, they take the form of the taboo in which they are placed. Gases, on the other hand, do not have both obvious volumes and obvious shapes. They take the volume and shape of the containers in which they are placed. The volumes of geometric shaped bodies are calculated by measuring the volumes and dimensions of geometric shaped, rectangular prism, cube, cylinder, sphere and cone shaped solid bodies. The volume of the prism of rectangles is equal to the product of three different edges. Volume = En . size . height V = a . b. C dir. The volume of a cube with all three sides equal and up to A is v = a3. The volume of a cylinder with a base radius r, height h, is equal to the floor area multiplied by its height. V = pr2 . h dir. The volume of a sphere with a radius r is the volume of objects that are not smooth the volume of solid objects that are not of a smooth geometric structure is found by using liquids in graduated containers. When such bodies are immersed in a container that is completely filled with liquid, they carry liquid in as much volume as its volume, provided that they do not melt in the liquid. If the object does not sink completely, the volume of the overflowing liquid is equal to the raw material of the sinking part. If an object is thrown into a liquid in a graded container that is not fully filled, it displaces the liquid in a volume equal to the volume of the object. If a solid object dissolves when thrown into a liquid, we cannot find the actual volume of the object. Because, just as the volume of a body in the solid state and its volume in the liquid state are not equal, there may be air gaps in the solid, and when it melts, the air comes out and the volume decreases. When water is poured over the dry sand contained in the graded container, the volume of the mixture becomes smaller than the sum of the separate volumes of water and sand. This is because there is an air gap between the sand grains and water fills these gaps. Accordingly, the actual volume of sand is found by subtracting the volume of water from the volume of the mixture. Volume units are Volume V symbol.
