Heat-n-Temperature.

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

Mole.

 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

why do cold drinks splashes out on sudden opening of its bottle cap?

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
