Root mean Square Velocity
Vrms=√3RT/M
Mean  Velocity
Vm=√8RT/&#960M
Most Probable Velocity
V=√2RT/M

Vrms > Vm > V

Average kinetic Energy of Gas=3/2nRT

First law of Thermodynamics

ΔU=Q-W


Gas Processes

Isothermal Process : PV=constant ,ΔU=0,Q=W,Molar Specific Heat=infinity
Adaibatic Process : PVy=constant,Q=0,ΔU=-W,Molar Specific Heat=zero
Polytropic Process : PVn=constant,Molar Specific Heat=[R/(y-1) + R/(1-n)]
Volume Constant : P/T=constant W=0,ΔU=Q,Molar Specific Heat=Cv
Pressure Constant : V/T=constant ΔU=Q-W ,Molar Specific Heat=CP

Internal energy depends on Temperature.
So for same temperature change ΔT
nCvΔT=Q1-W1=Q2-W2=Q3-W3

Molar Specfic Heat Capacity of any process is given by

C=Cv + Pdv/ndT where n is no of moles of the gas

Problem Solving tips
1.     Net Heat flow at a junction is Zero
2.     Internal Energy does not depend on the path
3.     Internal Energy in a cyclic  Process is zero
4.     Heat is positive when given to the system and negative when taken out of the system
5.     Workdone by the system on the surrounding is positive while the workdone on the system by the surrounding is megative

Laws of chemical combinations

Laws of chemical combinations

      1)      Law of conservation of mass:- According to this law “matter can neither be created nor destroyed” Given by Antone Lovoisin in 1789.
    2)      Law of definite proportion:- According to this law “A given compound always contains exactly the same proportion of elements by weight known as law of definite proportion or law of definite composition” given by Joseph Proust in 1754-1826
     3)      Law of multiple proportion:- According to this law “if two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of small whole number” given by Dalton in 1803.
    4)      Gay lussac’s law of gaseous volume:- According to this law “gases combine or are produced in chemical reactions they do so in a simple ratio by volume provided to all gases are at the  same temperature and pressure” given by Gay Lussac’s in 1808.
    5)      Avogadro’s law:- According to this law “Equal volume of gases at same temperature & pressure should contain equal no. of molecules” given by Avogadro in 1811.

Dalton’s Atomic Theory

 i.            Matter consists of indivisible atoms.
       i. All the atoms of a element have identical properties (same properties) i.e. atoms of a element have same mass while atoms of different elements have different masses.
       ii.Compounds formed when atoms of different elements combine in fixed ratio.
     iii Chemical reactions involve reorganization (rearrangement) of atoms.
Atomic mass unit = 1/12th mass of one carbon12 atom.
Molecular mass = It is the sum of atomic masses of the elements present in a molecule.
Mole :- It is the amount of substance equal to Avogadro no. (NA). = 6.022 ´ 1023 atoms/mole.
Molar mass:- Mass of one mol of a substances in gram is known as molar mass.
Mass % of an element = mass of that element in compound ´ 100/ molar mass of the compound.
Empirical formula :- It is the simplest whole no. ratio of various atoms present in a compound.
Molecular formula:- It is the exact no. of different types of atoms present in a molecule of a compound.

द्रव्य (Matter)

द्रव्य (Matter)

1. द्रव्य (Matter) क्या होता है?
– द्रव्य वह पदार्थ होता है जो स्थान घेरता है तथा जिसमें आयतन (Volume) या भार होता है

2.द्रव्यों की अवस्था (States of Matter) से क्या तात्पर्य होता है?
– द्रव्यों की अवस्था उनका वह विशिष्ट स्वरूप होता है जिसे वे प्राप्त करते हैं

3.द्रव्यों की चार मूलभूत अवस्थाएं कौन सी होती हैं?
– ठोस अवस्था (Solid), द्रव अवस्था (Liquid), गैसीय अवस्था (Gas) और प्लाज़्मा अवस्था (Plasma) – (ये चार अवस्थाएं द्रव्य की वे अवस्थाएं हैं जिन्हें हम रोजमर्रा के जीवन में देख सकते और महसूस कर सकते हैं। लेकिन इन चार आवस्थाओं के अतिरिक्त भी वैज्ञानिकों ने द्रव्यों की तमाम अन्य अवस्थाएं वर्णित की हैं जो अलग-अलग स्थितियों अथवा वैज्ञानिक प्रयोगों के दौरान सामने आती हैं)

4.द्रव्यों की वे कुछ प्रमुख अवस्थाएं कौन सी हैं जो वैज्ञानिकों ने उल्लिखित की हैं जो उनकी आम चार अवस्थाओं से भिन्न होती हैं?
– बोस-आइंस्टीन कण्डेन्सेट (Bose–Einstein condensate), फेर्मोइनिक कण्डेन्सेट (Fermionic condensate), सुपरफ्लुइड (Superfluid), क्वांटम हॉल स्टेट(Quantum Hall state), लिक्विड क्रिस्टल स्टेट (Liquid Crystal States), फोटोनिक मैटर स्टेट (Photonic matter state), आदि।

5.ठोस (solids) क्या होता है?
– पदार्थ जिसका आकार तथा आयतन (volume) निश्चित होता है

6. द्रव (liquid) क्या होता है?
– द्रव्य की वह अवस्था जिसमें उसका आयतन (volume) तो निश्चित होता है लेकिन आकार (shape) निश्चित नही होता है (उदाहरण के लिए किसी पात्र जैसे गिलास में रखा जल उस गिलास का ही आकार ले लेता है लेकिन बावजूद इसके उसका अपना आयतन होता है)

7.गैस (Gas) किस प्रकार के पदार्थ होते हैं?
– गैस वे पदार्थ होते हैं जिनका आकार (Shape) और आयतन (Volume) दोनों अनिश्चित होते हैं

8. प्लाज़्मा (Plasma) अवस्था वाले पदार्थों की विशेषता क्या होती है?
– इन पदार्थों का आकार (Shape) और आयतन (Volume) दोनों अनिश्चित होता है और इसके साथ ही अणु तटस्थ (Neutral) होते हैं (इसका तात्पर्य हुआ कि उनमें आयन (ions) और इलेक्ट्रॉनों (electrons) की पर्याप्त संख्या होती है जोकि मुक्त स्थिति में रहते हुए आसानी से अपनी स्थिति बदल सकते हैं- प्लाज़्मा में इलेक्ट्रॉनों का एक निश्चित अनुपात किसी परमाणु या अणु के साथ बंधे होने के बजाय स्वतंत्र होता है।)
