How can we Separate a Mixture of Two Solids Many of the materials around us are mixtures. These mixtures have two or more than two substances mixed in them. It may not be possible to use a mixture as such in homes and in industries. We may require only one (or two) separate constituents of a mixture for our use. So, we have to separate the various mixtures into their … [Read more...] about How can we Separate a Mixture of Two Solids
What is Sublimation in chemistry Sublimation : The changing of a solid directly into vapours on heating, and of vapours into solid on cooling, is known as sublimation. Sublimation can be represented as: The solid substance which undergoes sublimation is said to ‘sublime’. the solid obtained by cooling the vapours of the solid is called a ‘sublimate’. Ex. When solid … [Read more...] about What is meant by Sublimation and what are the Factors that Affect the Rate of Evaporation
What is meant by the Kinetic Theory of Matter? The Kinetic Theory of Matter: The arrangement and movement of particles in solids, liquids and gases are described in the kinetic theory of matter. The kinetic theory of matter is used to explain the changes in the states of matter. The changes in the states of matter are caused by heating or cooling. For example, ice … [Read more...] about What is meant by the Kinetic Theory of Matter?
