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 an Abiotic Component
What is an Abiotic Component Abiotic Components The word ‘abiotic’ means ‘non-living’. Light, air, water, soil, and temperature are some examples of abiotic components of the environment. Even though these components are themselves non-living, they have an effect on the living organisms, i.e., the biotic components of the environment.Light Plants use light to prepare … [Read more...] about What is an Abiotic Component
Measurement of Temperature
Which Instrument is Used to Measure the Temperature? Temperature is a measure of the degree of hotness of an object. A hot object has a higher temperature than a cold object. When two objects are in thermal contact, heat energy is transferred from the object at the higher temperature to the object at the lower temperature.Table shows a comparison … [Read more...] about Measurement of Temperature
What is Temperature and Can Temperature be Measured Directly
What is Temperature and Can Temperature be Measured Directly Temperature The degree of ‘hotness’ or ‘coldness’ of a body or a place is called temperature. One of the methods of measuring the degree of hotness and coldness is by the sense of touch. But our sense of touch can sometimes be misleading. Let us look at the following experiment to understand why!Activity Aim: … [Read more...] about What is Temperature and Can Temperature be Measured Directly
