The Logarithm Calculation is very much important for all of us. But for a student of science it is  like gift from god. A science student cannot take him away from calculation. Simple calculations can be done by by anyone but what about complex ones. Today we at eStudyan will give you all an important tool of mathematics which will help you in solving some complex problems.so let's start. Today we shall learn about logarithms. Logarithms can be used in finding any exponent of any number. Basically logarithm says us that at what power of given number we get a specific value. Suppose anyone says 10 raise to power 2 will give you  100 as result. In logarithm we represent this statement as   log 10 100=2. So it is clear that by logarithm we can find both power and the result we get after raising a certain number with some power. I hope you understood this. The tool logarithm has two types of table, log table and antilog table. We shall learn how to use these tables ...

Heat and temperature What happens if someone asks you to differentiate between heat and temperature. I know both senses same to most of the people. And in reality many one from you will declare these two words same. This is far away from truth. Heat and temperature are two different words which have two different meanings. Today we at eStudyan will discuss this topic. So, let's begin! Temperature The measurement of hotness or coldness of a body is termed as Temperature. There is so many scales on which we measures temperature such as kelvin scale , Celsius scale , Rankin scale , Fahrenheit scale etc. But its SI unit is kelvin scale. Although most commonly we uses Celsius or Fahrenheit scale but international system of units have given priority to kelvin temperature scale.  There is a very simple way of relating two units. One simple thing you have to know is the boiling and melting/freezing point of water at those particular scales. Now understand the way.  Suppose you want to...
