Basic Concepts of Chemistry Class 11| in Hindi

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. Extensive Properties: properties of matter that depend on the quantity of the matter observed (volume, mass, heat). Intensive Properties:-properties of matter that are independent of the amount of matter observed (density, temperature). Homogeneous mixtures: uniform throughout and include such things as solutions. Heterogeneous mixtures: not uniform; components of the mixture vary in concentration throughout the mixture. In this video, we will cover:
1. Basic Concepts
2. States of Matter
3. Macroscopic Level
4. Pure Substance
5. Mixture
6. Properties of Matter
7. System of Units
8. The International System of Units (SI)
9. Mass
10. Mass Vs. Weight
11. Temperature
12. Prefixes in SI units
13. Prefixes used in SI System
14. Derived Units
15. Uncertainty
16. Uncertainty in measurement: Precision & Accuracy
17. Scientific notation
18. Significant Figures
19. Uncertainty in measurement: Significant figures
20. Significant Figures: Operation rules
21. Conversion
22. Dimensional Analysis: Example
23. Laws of Chemical Combination
24. Avogadro Law
25. Dalton’s Atomic Theory

Batch 2024-2025 Attendance lgana mat bhoolna because we are legend 👇👇

[ADITYA_XD.]

If "CHEMISTRY" students start making films,

*Tera acid mera base
*Rang de benzene
*Humara beaker aapke pas hai
*Life in a Hetero
*Laaga apron me daag
*3 test tubes
*Ajab estimation ka gajab result
*Munna bhai HCL
*Mr. Ketone
*Jab we experiment...!

😜😜Dialogue baazi in chemistry..
*My name is BOND...Covalent Bond!
*Rishtey mein to hum tumhare Allotrope lagte hain, naam hai...Diamond!
*D-block se darr nahi lagta saheb, F-block se lagta hai!
*Ek baar jo maine bond toda to main activation energy ki bhi nahi sunta!
*Resonance ko neglect karna mushkil hi nahi na mumkin hai!
*Ye electron mujhe dede Carbon!
*Ek neutron ki keemat tum kya jano Hydrogen Babu!

To all science students
😂😂😂😂😂😂😂😂
