Free Tutorial in Basic Physics - Heat and Temperature
There are many basic concepts in Physics, understanding of which helps the students to gain knowledge in this subject. Learning about heat energy and its transmission from one place to other is one of such areas and this article tries to explain it in detail.Learn Science - Oxygen and its chemistry
Oxygen is very abundant in the atmosphere and 89% of the seawater is oxygen only. Oxygen is essential for all animals and human beings. Plants use carbon from the carbon dioxide and leave oxygen out. That is how we are getting oxygen for our living free of cost. The chemistry of oxygen is discussed in this article.The Chemistry of halogens
Halogens are very reactive elements. They belong to VII A group of the periodic table. Among the halogens, Fluorine, Chlorine, Bromine and Idoine are very well known and find many applications. The chemistry of these elements is discussed in this article.Different crystal structures of Engineering materials
This article describes the basic crystal structure of common engineering materials which are now basic building blocks of daily life. Engineering materials like Aluminium, copper, Iron, Cobalt, etc are made up of different types of crystal structures like BCC, FCC, and HCP. Each structure has its own unique arrangement and based on atomic radius and atomic distance, the different crystal structure has different density and so on for other material properties.Free Tutorial in Basic Physics - Mass and Weight
