30:00 sir el aur tareeka hai Ham dono me ice dal denge , normal water me ice equally float kargi aur salty water me on the surface float kargi because density ko water is same as that of ice but density of salty water is higher than that of ice Sir please tell wheather my answer is right or not because it's my exam tomorrow 🙂🙃🙃

Sir air to heterogeneous hai kyuki ismai dust bhi hota hai jo ki ham tyndel effect se dekh sakte hai agar ham scattering krenge to hame dust yani ke particles dikhenge

Thank you sir ji 9th waalo ki madad krne ke liye🙏🔥🔥🔥🔥
30:00:- distillation hoga kya sir..... ( evaporation se water evaporate krke condensation se water aalag kr lege aur uske bad racidue check kr legen.. )
Sir in 1st ques all options are wrong because 118+273 is 391
Yes

30:00 crystallization is better than evaporation
5:44 .... Started ...
25:12 answer (c) because c has more surface area and more speed air helps to fan
Bro but water bhi jada hai na (c) m (b) ke comparison me
🥴
Sir ne to btaya ni hai ki dono m same water hai
Sir first question 273+118 gives 391K please tell
Yes you are right and am thinking it too
Solute- sugar
Solvent -water
Sir 7:59 option b and both are correct✅ 😂
I'm watching it before my Hindi exam😅
1 ques ans (a)
Because 118 + 273=391
Crystallization se without tasting
30:00 sir el aur tareeka hai
Ham dono me ice dal denge , normal water me ice equally float kargi aur salty water me on the surface float kargi because density ko water is same as that of ice but density of salty water is higher than that of ice
Sir please tell wheather my answer is right or not because it's my exam tomorrow 🙂🙃🙃
answer sahi h but teacher marks deduct kar sakte h kyuki density ka topic alag hai
Sir, after watching this video, I do not need to read the book.😊😀

Sir mujhe be online classes chahiye from science and fun by you😊
Boiling point pta lga lenge aur pani ka clour bhi pehle se thoda dark ho jayega usse bhi pta lga lenge
Sir 1 ka answer to 118+273 = 391
Surface area increase evaporation
Thank u Sir 🙏

Sugar is a solut and water is a solvent
Isme se teen se char questions mere exam me aaye the thanks sir
Batt to sahi hai
30.45 sir uss meen to PH value bhi check kar ke pata laga sakte hain
Sir we can find out that which is having salt or sugar by using evaporation too. By evaporation, we can separate the salt and sugar from water.
16:45 sugar solute or water solvent

53:13 sir valency of x will be +2 as it is gaining electron and
Valency of y will be -2 as it is losing electron
No it doesnt work like that bro your concept isn't clear
Nope! This concept is just opposite of that you're thinking.
sirri h kya padhke aa fir gyan dena brother :\
Lekhna to Sikh le phle
Sir pls physics ka numerical ki bhi vedio bana do pls pls sir
Mole concept please 🥺

Sir in the first question 118 + 273 is 391 not 392
Just a lil mistake no worries

Yes 391k right answer h
Water solvent hai and sugar solutes
Thank you so much sir

7:02 answer is wrong sir 118+273=391 hota hai or aapne options mai 392 de rakha hai
10:12
1 question ka answer glat hai .
The correct answer
35+273=308k
56+273=392k
118+273=391k
No any options are correct .the correct option is this
2N^2 mole and nitrogen gas hai
2 moles of nirogen gas
7:53 sir none of them is correct
118+273=391 not 392

Is cbse class 9th annual exam question paper set by cbse or school board?
School
sir question number 1 mai toh 118 diya hua hai na toh 118+273 toh 391 hota hai options galat hai sir
8:04 sir 273+118 =391k ho raha hai shayad aapke option mein kuch galat hai
Sugae is solute
Sir air to heterogeneous hai kyuki ismai dust bhi hota hai jo ki ham tyndel effect se dekh sakte hai agar ham scattering krenge to hame dust yani ke particles dikhenge
Same question
Pure air is homogeneous because
1. We can't see the components present it it to the naked eye
2. Components cannot be separated easily
Air is homogeneous because the ratio of different gases in air is always fixed, i.e. Oxygen= 21%, Nitrogen 78%, etc
