[@sweetymalik7409]

Ma'am which solvent is taken as the standard solvent for the solid phase?
Is it the same solvent which is used in making solution or something else?
And if is the same solvent then why the curve of pure liquid solvent and standard frozen solvent not same? Bit confuse!

[@the_lawschool]

Mam latent heat of vaporisation???

[@defence_addicted..]

Mam temperature or vapour pressure directly proportional hota hai kyuki temperature 🌡️ badhega toh vapour jyada bnaye kyuki solution ki solubility kam ho jye ge

[@preetikaschemistry]

True 👍

[@Vicky-Bio.theo-aris]

Thank you Mam your way of explaining is very good

[@preetikaschemistry]

Thank u mam❤😊
Mam aap se request hai please Polar solute & Polar solvent ke bare me bta dijiye🥹. Bhot problem ho rhi hai😢

[@armansharma172]

Thx mam
Last one please 🙏

[@defence_addicted..]

Mam ya frozen solvent ka matalab solid phase sa h kya matlab same temperature per pure solvent fast sa freez hoga or usma jyada vapour bnaga or solution ma same temperature per solid phase ma ana ka liya temperature kam chaye per temperature kam chaheye toh jaldi freez hoga na

[@preetikaschemistry]

You are right but last line m confuse ho gye... Solution ko solid state(frozen state m laane ke liye temperature Kam chahiye. Toh abhi at present hum room temperature pr hai toh hame solution ko freeze karne ke liye temperature ko bhot zyada niche Lana padega isliye solution late freeze hoga than pure solvent. Hope you got it 🙂👍

[@defence_addicted..]

Mam your explanation is just amazing right now i am studying for boards and its making me very clear mam and mam i had a doubt that after boards i have my neet so can i study this for my neet or if you can make special one shots or something for neet mam please it will be very very helpful mam i am in love with your explanations mam please please please i request you...❤️❤️

[@preetikaschemistry]

Yes the theory will be helpful for you, and try to practice more and more questions

[@urjavlogs8502]

[@armansharma172]

Mam tf of solvent greater then tf of solution kyu aayea,freezing point of solvent to decrease ho raha hai na😓

[@preetikaschemistry]

Nhi diagram m dyaan se dekho Tf° x-axis ko zyada value pr cut kr raha hai. And Tf Kam value pr hai. Tell me if you get it

[@armansharma172]

Nahi mere kehne ka mtlb tha ki horizontal pe temp->and v.p.up ki Direcation mein kyu dikhayeya hai😅

[@preetikaschemistry]

Bache x- axis m mujhe btao pehle ki Tf°(solvent) kha cut kr rha hai... Right side ko tf° hai and left side ko Tf

[@preetikaschemistry]

Aapko x-axis pr focus Krna h ki temperature zyada value pr cut kr rha hai ya Kam value pr.. btaoo aapko aayaa samjh

[@armansharma172]

Thik hai mam samj aa geya🙏

It's Gas constant.

[@user-qz2fe6se2l]

R=8•314J/k mol

[@JDS140]

Hey Mam,First of all Thanks a lot your videos are very helpful,Also I have a request Mam if You teach Thermodynamics Because in 11th it is the only chapter in which I am not confident.

[@preetikaschemistry]

Will try 🙏

[@rohitmahto9021]

Achha samjhaye hai madam jii

[@armansharma172]

Mam is ke digram mein to temp and v.p. ko ulti tarf kyu bata rehe hai

[@preetikaschemistry]

Kyunki temperature decrease krte hai isme to reach the freezing point.

[@armansharma172]

Nahi vo to mai samj geyA pr hm digram mein ye kyu dikha rehe hai ki temp. increase ho rha hai arrow ke sath

[@defence_addicted..]

Mam temperature or vapour pressure directly proportional hota h kyuki agar temperature 🌡️ badhega toh vapour jyada bna ga kyuki unki solubility kam hogi

[@armansharma172]

[@defence_addicted..]

​@@armansharma172 samj aya kyaa kuch kyuki ya main sahi bta rahe hu ya nahi ya mana mam sa pucha tha 😅

[@user-ip1yw4yd3y]

Mam what is the vapour pressure of solid solvent??

[@preetikaschemistry]

Vapour pressure of solid is very low because of the strong intermolecular forces present as compared to liquid and gases.
