We know that friction is the resisting force that exists between any two surfaces in the opposite direction of the motion. Friction is between solid surface, layers of fluid, and also between any two materials. If there is no friction then most of the tasks such as walking on the road, writing on a board, sliding of the table, etc would become difficult. Therefore, friction is one of important forces that is needed for a smooth life.

Let’s observe the factors of few natural numbers.

We can see that number 1 has only one factor (i.e. itself).There are numbers that have exactly two factors i.e.1 and the number itself. Such numbers are 2, 3, 5, etc. These numbers are prime numbers. A number is called prime when it can't be divided evenly by any number except 1 or itself.

They're able to bond with the water molecules. ... The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water.
