Vaporization is a process of phase transition in which a substance, changes its state from liquid to vapour. It can take place in two ways, i.e. evaporation and boiling. The process of evaporation involves phase transition at a temperature below the boiling temperature. On the other hand, boiling of a substance takes place at boiling point, which may vary with the change in the environmental pressure. Water boils at 100°C, and the temperature does not rise even if heat is continuously … [Read more...]

The primary difference between flora and faund is that flora talks about the plant life of a region or a certain period whereas fauna represents the wildlife of a region or specific period. Earth is the only planet in the entire universe, that can support life. In fact, it is a home to millions of life forms. The variety of plant and wildlife, in the world, is known as biodiversity. Wherever we go, we find a different variety of plants, flowers, birds, insects, animals and other … [Read more...]

Agriculture is one of the primary occupations of all the countries around the world. Indeed, we are mainly dependent on agriculture for our daily needs. To increase the agriculture produce, the farmers work on improving the fertility of soil, which is possible by adding manure and fertilizer. Manure refers to the natural substance that is obtained from the decomposition of the waste of plant and animals such as cow dung, etc. On the other hand, fertilizer is the chemical substances which can … [Read more...]

Fog and Mist, both are clouds made up of condensed water vapour, i.e. water droplets, hanging in the atmosphere at the surface of the earth, which restricts visibility to some extent. In spite of having similar composition, there are subtle differences between fog and mist which lies in the density and extent to which the visibility is reduced. Fog is denser in comparison to mist, and so it has a greater impact on visibility, i.e. the former limits visibility to nearly one kilometre, but the … [Read more...]

Balanced force implies the force which does not change the object's state of motion. On the contrary, unbalanced forces are the one that results in the change in object's state of motion. Have you ever observed that whenever you want to move an object, it is either pushed or pulled? In physics, the motion exerted (push or pull) to the object, is termed as force, which arises due to the object's interaction with another one. It is capable of changing the object's magnitude of velocity, the … [Read more...]

When you look around, you will find an array of objects with different size, shape and texture. These objects are made up of matter, which is present in three forms i.e. solid, liquid and gas. All three states of matter possess two things in common, which are mass and volume. Mass is the quantity of matter while volume is the measure of space occupied by the object. The ratio of these two aspects of the matter is known as density. The measurement unit of mass is a kilogram, whereas the … [Read more...]

The basic difference between uniform and non-uniform motion is that the former represents the motion in which the moving body covers the same distance in the same time, but in the case of latter, the body travels unequal distances at the same time. There are millions of objects surrounding us, some of them stay at rest while others are in motion. In our day to day life, you have noticed the motion of different living and non-living things that are on the move like birds, fishes, cars, buses, … [Read more...]

Weather plays a significant role in our lives, as most of our day to day activities are planned according to the forecasting made by the meteorological department for a particular day. It is the intricate phenomenon, which demonstrates changes over very short periods of time, in the atmospheric condition at a given region. On the contrary, climate indicates the weather pattern of a particular place, taken over a long time. Often perceived as being the one and the same thing, these two terms … [Read more...]

The process in which heavy nucleus is broken into tiny nuclei, is called as nuclear fission. On the other extreme, nuclear fusion is defined as the reaction wherein lighter atoms come together and form a heavy nucleus. With the rapid industrialisation, our demand for energy is increasing in the same ratio, because of the change in the way we live and do our work, as we are greatly dependent on machines to do our work, which consumes energy. It implies the strength and power that we require to … [Read more...]

Velocity and acceleration are the two key concepts which are always discussed while studying motion. Velocity can be understood as the speed of a moving body in a particular direction whereas acceleration is any change in the velocity of the object, with respect to time. Motion implies movement; it is the act of moving or more specifically, the change in position of the body, concerning time. Whenever you walk, run or drive you are actually in motion and not only this, flying of birds, … [Read more...]
