Sir Ma Sh Allah ap bohat acha guide karta han ka 1 part samjh kar dosra ma khud solve kar lati hon or ap hamara clg ka teacher sa bi acha a guide karta han thanks you
excellent sir but a random q pops in my mind that if u taking a brick and some how by putting pressure to it and covert it into a small block brick than its weight /mass will be changed or not idk its a weird q 😅😅
Greater the volume means more appart molecules from each other, so have more kinetic energy they have to diffuse..... As we know gases diffuse rapidly due to their large volume compared to liquids or solids
Sir plz🙏🏻 tell that under what conditions we will convert unit of volume into dm3 or cm3 Cuz in some numerical it is converted into dm3 and in some it is taken as such
when you have to put value of R = 0.0821 atm dm3 mol-1 k-1 in your any formula then you have to convert unit of volume into dm3 and unit of pressure into atm cuz unit of R are atm dm3 mol-1 k-1. Otherwise for formulas like p1v1=p2v2 both the units of volume and pressure have to be same and you will the answer in that unit in which you have you have put the values. For question 17 part A you have to put all the values in SI units. Hope it is helpful.

Ohhh sir g tusi great ho!! ❤😊
excellent sir but a random q pops in my mind that if u taking a brick and some how by putting pressure to it and covert it into a small block brick than its weight /mass will be changed or not idk its a weird q 😅😅
Density will change but mass will not because mass is the total amount of matter which remains constant during thia whole process
Sir khi py no. Of moles ka formula "mass/molar mass" hota h to khi isko avagrdeo no. Sy multiple krty hain hmy kesy diff pta chly ga???
Wo no of moles ka hota hai hamy no of molecules chahiye tab. Hm no of (moles) ko Avogadro's number SE × krty hn
Exactly 👍
Ap ky wahaja sy meri test ki achi preparation hogi hy

Jazakallah sir Allah will give uh the reward insha'Allah ❤

Amazing leacture...👍
Q not 21 mei Rate of diffusion of hydrogen c part mei 1 kexe aya? Can you explain it again.?
Sir why rate is directly proportional to volume?
Greater the volume means more appart molecules from each other, so have more kinetic energy they have to diffuse.....
As we know gases diffuse rapidly due to their large volume compared to liquids or solids
Sir imp chptrs bta dein long questions ky according??
Sir please tell me how we know that in question no 21 part c ka H2 ko upper put karna ha ya nachay
Larsha pekhawar
Niche
If you put rate above then put the molecular mass below as according to Graham's law

Outstanding Dear sir !Thank you so much sir ❤
Sir plz use whole method
Sir your teaching method is too much good
Sir plz🙏🏻 tell that under what conditions we will convert unit of volume into dm3 or cm3
Cuz in some numerical it is converted into dm3 and in some it is taken as such
Sir plzz reply to this ques...
when you have to put value of R = 0.0821 atm dm3 mol-1 k-1 in your any formula then you have to convert unit of volume into dm3 and unit of pressure into atm cuz unit of R are atm dm3 mol-1 k-1.
Otherwise for formulas like p1v1=p2v2 both the units of volume and pressure have to be same and you will the answer in that unit in which you have you have put the values.
For question 17 part A you have to put all the values in SI units.
Hope it is helpful.
