In lever, there are three different ways of arranging effort, load, and fulcrum. Therefore, depending on the relative positions of the fulcrum, the load, and the effort there are three different types of levers....
A machine is a device that allows us to do work with less effort. It helps us to lift heavy loads or speed up the motion, or change the direction of a force. In...
In chemistry, a mixture and a compound are two different states of a substance. In this post, we will learn about these two states and try to find out what is the difference between...
Reactivity series of metals and nonmetals are the lists, in which we arrange them in the decreasing order of their chemical activity. It is also known as the activity series. The reactivity series helps...
In chemistry, we categorize all materials around us as – pure substances and mixtures. Mixtures are further classified as – homogeneous mixture and heterogeneous mixture. In this post, we will learn about the characteristics...
There are different types of chemical reactions – hydrolysis, oxidation, synthesis, reduction, combustion, electrolysis, neutralization, etc. However, we can classify all types of reactions into the following categories: Combination or synthesis reaction Decomposition reaction...
The definition of a pure substance in chemistry is not the same as that of what we use commonly. Most of the substances, in our daily life, which we assume as pure are not pure...
Living things are made up of tiny living parts or compartments called cells. The cell provides structure and performs all life functions of living things. However, a single cell working on its own would achieve...
For a body in motion, both speed and velocity are the quantities by which we know how fast the body is moving. Although they seem similar, there is a difference between the two. In...
