POSTULATES OF KINETIC THEORY OF GAS.
• A gas is made by very small particle which are known as molecules.
• All the molecules of gas are identicle smooth regid and perfectly elastic.
• Average velocity and average momentum is zero.
• A gas is made by very small particle which are known as molecules.
• All the molecules of gas are identicle smooth regid and perfectly elastic.
• Average velocity and average momentum is zero.
• Molecules of own collide themselves and with the wall of container and there collision is perfectly elsatic.
• Time of collision is neglect in comparision to time between two sucessive collision and there ration at standard temperature and pressure is 10^-8 : 1.
• Intermolecular force between there a molecules is except during collision.
• Molecules are point masses hence there volume can be neglact in compair to container.
• volume of gas = volume of container.
• Due to neglet mass and high speed effect of Gravity of molecule is neglet but they follows Newton's law of motion.
• In these assumption number of molecules are assume to be large 10^23.
:EXPLATION IN HINDI :
• A gas is made by very small particle which are known as molecules.
€ Gas hamesa compound k form me paya jata hai hamare atmoshphere me so smallest part of compund known as molecule".
• All the molecules of gas are identicle smooth regid and perfectly elastic.
€ Gas molecule ko aek shape ka mana jata hai"
• These molecule contineously moves in random motion following zig zag path . This type of motion of molecules is called Brownian motion.
€ Gas molecule hamesa gati me hota hai bole to hamesa ghumta hi rahata hai jo ki koi bhi nischit rasta nahi hota hamesa tedha medha ghumta hi rahata hai jinko randam motion kahate hai.
• Average velocity and average momentum is zero.
€ Yaha jo Average velocity zero bataya gaya hai or momentum zero bataya gaya hai kyoki isme total displacement zero hota hai ,Ham jante hai ki Average velocity equal to hota ha Total Displacement batta Total time or yaha total displacement zero hota hai kyoki aey jo Assumption mana gaya hai aek close container me liya gaya hai jo gas hamesa motion me hota hai jo ki initial and final point k bich ka displacement zero hota hai .kyoki gas molecule jaha se chala hai generally rebound ho kar phir ohi pahuch jaata ha."
• Molecules of own collide themselves and with the wall of container and there collision is perfectly elsatic.
€ Perfectly elsatic collision matalab hota hai jab aek gas molecule dusare se collide karta hai to total energy loss jo hota hai oh zero hota ,matalab total energy loss kuchh bhi nahi hota hai .Yadi aesi koi bhi Collision hoti hai to use perfectly elasatic collision kahte hai.
is case me
e (Coefficient of restitution) = 0
hota hai,"
• Time of collision is neglect in comparision to time between two sucessive collision and there ration at standard temperature and pressure is 10^-8 : 1.
• Intermolecular force between there a molecules is except during collision.
€ Matlab Gas molecule k aapas me koi bhi Aakarshan Gorce nahi hota hai.
• Molecules are point masses hence there volume can be neglact in compair to container.
€ Ovious si baat hai aek gas molecule ka volume as compair to container neligible hoga."
• volume of gas = volume of container.
€ Hamesa for calculation purpose Volume of us container ka volume lete hai jis container me oh gas rakah hua hai"
• Due to neglet mass and high speed effect of Gravity of molecule is neglet but they follows Newton's law of motion.
€ Aek gas molecule ka weight itna kam hota hai ki usper gravity force ka kitna amount lagta hoga .Aek to aese hi Garavity force weakest force .But yaha per Newton's k 2nd Law Applicable ya lagu hota hai"
• In these assumption number of molecules are assume to be large 10^23.
