Question

1) What is the scientific name of particles which makeup matter?
2) Name the process by which a drop of ink spreads in a beaker of water?

Answer 1

Hint: The scientific name of the particle which makeup matter are atoms or molecules. Further atoms are divided into protons, electrons and neutrons and they are made up of quark. The process through which a drop of ink spreads in a beaker of water is known as diffusion.

Complete answer:
From your chemistry lessons you have learned about the matter and the makeup of matter and also about the diffusion process taking place.
Let us discuss each question given above one by one:
1) What is the scientific name of particles which makeup matter?
As we know that matter is any entity which can occupy space and has mass. Matters are of different kinds which can exist in any of the three forms such as solid, liquid or gas. It is made up of tiny particles and these tiny particles are so small that they cannot be viewed by naked eyes.
Matters are the makeup of particles which is known as atoms or molecules. And all the particles are in motion. Atoms are further divided into proton, electron and neutron which is made up of quarks.
Thus, the scientific name of the particles which makeup matter are atoms or molecules.

2) Name the process by which a drop of ink spreads in a beaker of water?
The process through which a drop of ink spreads in a beaker of water is known as diffusion.
As we know that particles present in the matter are always in motion. Diffusion is defined as the movement of substance from an area of higher concentration to the area of lower concentration. The medium in which diffusion can take place is of three physical states like solid, liquid and gas. The interaction between the material and medium determines the speed of diffusion.
Now, if we will intermix the particles of two different matters such as ink and water on their own then the process is referred to as diffusion. Due to the random motion of water and ink the diffusion of ink in the water takes place. Here, ink moves from the area of high concentration to the area of low concentration.
Thus the process is known as diffusion.

Note:
The speed of diffusion is fastest in gases than the liquid and slowest in solid. The rate of diffusion also depends on the mass of the matter. Matter with larger particles moves in lower speed and therefore the speed of diffusion is slow. And with the increase in temperature the rate of diffusion of particles inside the matter also becomes fast due to the increase in kinetic energy.
