Yogita Ingle 7 years, 10 months ago

A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms. The atoms of certain elements readily bond with other atoms to form molecules. Examples of such elements are oxygen and chlorine. The atoms of some elements do not easily bond with other atoms. Examples are neon and argon.

Why are caterpillar tracks used in battle tanks instead of tyres

Posted by Anuradha Sharma 7 years, 10 months ago

CBSE > Class 08 > Science

1 answers

Yogita Ingle 7 years, 10 months ago

Weight of a battle tank is very huge. If they used wheels, they would often get stuck. Therefore in order to spread their heavy weight on the ground, they use caterpillar tracks in place of tyres. Battle tanks use caterpillar tracks to spread their heavy weight on soft ground. This prevents the sinking of land under the weight of the tank .
