HOW TO SOLVE NUMERICAL PROBLEMS IN CHEMISTRY OR PHYSICS 



In this post we will see how to solve numericals problems in chemistry or physics?

This video will explain you in detail that how to solve numericals problems in chemistry or physics.

This video will teach you about how to solve numericals problems in chemistry 

This video also teaches you about how to solve numericals problems in physics 

How to solve numericals problems?

Step 1 : Learn the formula.
Step 2 : Learn the concept of formula.
For example 
this formula is of 11th std of chemistry 
PV=nRT 
In this formula Learn about that in this formula 
What is P?
What is V?
What is n?
What is R? 
What is T 
Here 
P is the pressure 
V is the volume 
n is the number of mole 
R is the gas constant 
T is the temperature 
Step 3: Do the easy solved examples given in the textbook or any book which you prefer.
If you can not solve the given problem by own then clear your concept again and Learn the formula.
If you have solved the problem by your own then move to step 4. 
Step 4: Do the hard solved examples given in the
Textbook or given in the book that you refer. 
If you can't solve the problem than go to concept and clear you concept properly. 
If you can solve the problem then go to step 5 
Step 5: Do the easy numericals given in the exercise.
If you can't solve that problem then Clear you doubt with your teachers. 
If you can solve the problem then go to step 6.
Step 6: Solve the hard numericals given in the exercise.
If you can solve the hard numericals from exercise then you can also solve the moderate level exercise from textbook.

What is matter ?

What is matter ?    Matter is a term used in physics or chemistry to refer to anything that has mass and occupies space. In other words, it is the substance of which all physical objects are made. This includes everything we can see, touch, and interact with in the universe. Matter is composed of elementary particles, the most common of which are atoms and molecules. Atoms are the basic building blocks of matter, and they consist of a nucleus, composed of protons and neutrons, surrounded by electrons. Molecules, on the other hand, are groups of atoms chemically bonded together. There are four fundamental states of matter: 1. Solid: In solids, atoms or molecules are tightly packed and have a fixed shape and volume. The particles vibrate around fixed positions. 2. Liquid: Liquids have a definite volume but take the shape of their container. The particles in liquids are still close together, but they can move more freely than in a solid. 3. Gas: Gases have no fixed shape or volume and ca

Molar : Understanding the Concept and Its Significance

Demystifying Molar: Understanding the Concept and Its Significance Introduction: In the field of chemistry, the concept of the mole, often referred to as "molar," serves as a fundamental unit of measurement. The molar is a crucial concept that allows scientists to quantify and understand the relationships between atoms, molecules, and reactions. In this blog, we will delve into the fascinating world of moles, exploring their definition, significance, and applications in various aspects of chemistry. What is a Molar? Simply put, a molar is a unit of measurement used in chemistry to quantify the amount of a substance. It provides a bridge between the microscopic world of atoms and molecules and the macroscopic world of everyday measurements. The molar is defined as the amount of a substance that contains as many entities (atoms, molecules, ions, etc.) as there are atoms in exactly 12 grams of carbon-12. This definition is based on Avogadro's number, which is approximately 6

Unveiling the Science Behind Washing Powders: Insights from a Chemist

Unveiling the Science Behind Washing Powders: Insights from a Chemist Introduction: In our everyday lives, we encounter numerous challenges, and one that most of us can relate to is laundry. The quest for cleaner, fresher, and more vibrant clothes has led to the development of various laundry detergents, including the ever-popular washing powders. As a chemist, I find the science behind these powders fascinating. In this blog, we will delve into the intricate world of washing powders, exploring their composition, working mechanisms, and the chemical reactions that make them effective . 1. Composition of Washing Powders: Washing powders are complex mixtures of chemicals carefully formulated to remove dirt, stains, and odors from fabrics. The composition of washing powders typically includes the following key components:  a. Surfactants:  These are the primary cleansing agents in washing powders. Surfactants contain both hydrophilic (water-attracting) and lipophilic (oil-attracting) prop
