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 in this article

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 rela

 Welcome to all of you in our today's article. This will be a very short article but don't worry it will not bore you. If you love math you will love this article. Let's begin. Fact:-  " if you multiply consecutive numbers  by a same number number their difference will provide you that number." (You can also refer to video provided below.) Now let's understand what i said. Suppose you multiply 2345 and 2344 by same number 9. See below:-            (2345×9) - (2344×9 ) By solving above expression you will get same number 9. Isn't it interesting . Try proving above facts with some more examples. Good bye see you soon with another interesting science or mathematics facts.

In today's world it's impossible to live without phones , TVs and other electronic gadgets. We need electricity to operate these gadgets. But have you ever thought how electricity reaches  to our house. Well today, we at eStudyan decodes this topic for you. The electricity supply board of our city provides two wire in our area and tied them to electric poles of our area. In these two wires one is live wire and other is neutral wire. These two wires reaches our house 🏠. Now an electric meter is fitted in our home by the electric supply board. This meter measures the amount of unit of electricity consumed by us in a given month. And in accordance with that they provide us suitable electric bill to us.  These two wires now gets connected to two separate fuses , one before getting into electric meter and other before reaching to the consumer's circuit.  We also connected fuse in our room circuit for safety. Now after passing from electric meter these two wire are provided to c

 Hey guys , hi. Welcome to another article presented by eStudyan. In this article we will discuss everything related to mole concept. This is a very demanded important topic for those who takes science in intermediate. Mole , molecule , molar mass etc. , These types of words haunts many students . And ,infact they do not understand this well after the end of their study also. If you also fear from mole then just read this full article. This will clear all your doubts  today. So let's start. Mole is just  a number.  It just tells us how much amount of particles present in a single atom. Suppose you went in market and you want to buy banana. The thing you will do there is you ask the banana seller to provide you banana. Then, he will asks you how much dozen banana you want.                       The dozen above means 12. Just like dozen in the above case , mole means 6.022×10 23 .  So now it should be clear that mole is just a number.  After the discovery of atom by John Dalton, sci

B allet dance, one of the most entertaining form of dance that we like to watch. If you had ever watched ballet , you must had watched the performer to rotate rapidly at one place. But have you ever thought how she do that easily. What is the technique behind this, that a normal person don't know and fails to perform this act.So let's explore this topic today. But before that we have to be clear about some basic concepts of motion of a body. So let's begin that first step by step:- 1.Momentum as you all know is the product of the mass of an object and it's velocity. This definition of momentum is limited to the linear motion of the object. But when the  object is rotating about an axis, it is undergoing rotational motion.                   It should be clear that rotational analogue of momentum is called angular momentum. We should now learn about the conservation of momentum which states that:- "Momentum neither be created nor be destroyed". So from the above

During a  hot summer day it feels relaxing to drink cold drinks such as:- pepsi, Coca-Cola etc. But when we open the bottle cap the cold drink seems to be splashing out with high pressure. Have you ever thought why it happens ? If yes then this article is for you. So let's start our today's explanation.                But wait! First of all we should be clear about its composition. So first let's see that:-  Aerated drinks (or cold drinks) mostly contains sugar and additives in them which enhances their taste. It contains carbon dioxide dissolved under very high pressure inside the bottle. Due to so much amount of sugar and carbon dioxide it is not advisable to take more aerated drinks. You can refer soda instead of it.                       It this carbon dioxide which feels us fizz on drinking.  It is this carbon dioxide which splashes out at very high pressure on opening the bottle caps. How this happens let's see:- The solubility of gases in liquids is directly pro
