Question

Select the characteristics of particles of matter.
A.There is enough space between particles of matter
B.The particles of matter are continuously moving about their mean position
C.The particles of matter attract each other
D.All of these

Answer 1

Hint:The particles of matter have several properties like the space between them, attraction force, movement due to kinetic energy, etc.

Complete answer:
Characteristics of particle of matter are as follow:
When we mix two different types of matter like we mix sugar and water, we obtain a sugar solution in which sugar is evenly distributed among the particles of water and if we mix sand in water we get a heterogeneous solution but still particles of sand manage to occupy space among the particles of water. This justifies that particles of matter have enough space between them. The extent of space present between the particles depends on the state of matter whether it is solid, liquid or gas.
At room temperature, particles of matter exchange heat with surrounding and due to this they possess some kinetic energy and this kinetic energy of particle increases with increase in temperature of surrounding. Due to this kinetic energy, particles of matter are continuously moving about their mean position.
As we can see particles of solid are held tighter than the particle of liquid and gases, due to this solid do have fixed shape and volume. On the other hand particles of liquid are held tighter than that of gases due to which liquid possesses fixed volume but not fixed shape. In case of gases, particles are so loosely bound due to which gases have neither fixed shape nor fixed volume. This states that particles of a matter have force acting between them. This force keeps the particle together. The strength of this force of attraction varies from one kind of matter to another.

Thus, the correct option is D.
Note:
Matter is defined as an object or substance that has mass and which can be felt by any of our five senses. Example: air, food, stone, cloud, water, sand, etc. All the matters are made up of particles. The size of particles in a matter is extremely small as a few masses of matter can have millions of tiny particles.
