guys ..there is some confusion in physical and chemical reactions from my side ...lets revise that again tomorrow...till then correct pdf has been uploaded ...plz look at them
yes mam, in the beginning, you have spoken that melting of ice is a chemical change, but it is a physical change....koi bat nhi hota h kavi kavi....but i like your classes of ntpc and also your such a dedication for us. thanks SIPRA mam, thanks WI FI study..and also thanks JIO
Chemical reaction me dobara waps aa b skta hai.... Hydrogen jlne pr water bnta h and heat nikalti hai. Electrolysis se dobara hydrogen and oxygen ko alg kr skte hai. Same in gypsum to plaster formation and vice versa but it is chemical process
In burning of candle as well the burning of thread isn't the only chemical change as well the wax that melts down in form of liquid and it is used as fuel as of petrol and that liquid burns and that is the chemical change in burning of candle
Mam 1 to 118 eliments ka video aapne kahan upload kiya hai saturday ko...? Please bataiye... Link dijiye...mil hi nahi raha hai video vahan par.. Please mam
1) Melting of Ice 2) Vapourisation of Water 3) Dissolution of Sugar in Water The above all are examples of Physical changes not the Chemical change or Chemical Reaction. Kindly correct me if I am wrong but I am 101% sure that I am right.
I know it's an old comment but I wanted to know if you have all the chemistry PDFs of ntpc. I had them all but recently got my laptop crashed and lost all the data. If you have it. Please reply. My cgl tier 2 is march 2🙏
मैम आपने बोला कि किसी रासायनिक अभिक्रिया में जो पदार्थ बन गया उसे वापस शुरू की हालत में नही ला सकते, तो शुरू में चीनी का पानी मे घुलना रासायनिक अभिक्रिया कैसे हुई?? ये रासायनिक और भौतिक परिवर्तन है जिनको आपने अभिक्रिया नाम से बदल कर पूरा मामला उलझा दिया!!
Melting of ice and vaporisation of water is not a chemical reaction,it is a physical reaction.agr aap acha se parhi hoti to ye basic mistake nhi karti.
चीनी का पानी में घुलना , रासायनिक क्रिया है बताया था आपने। लेकिन quiz में भौतिक क्रिया दिखा रहा है। और पिघलने की क्रिया को संलयन कहते है क्या , ये सही है क्या।

Melting of ice ko agar ice pighal jaye to usse fr ice to bna skte Hain pr mam aapne Bola ki jise dubara usi form m ni laya j skta but ice ko to laya j skta h
Melting of ice,Vaporization of water is a chemical reaction but burning of candle is the example of both physical and chemical reaction...since we can make candle from wax...in the same way we can convert ice to water and vice-versa. So how is it not a physical reaction insted of chemical reaction? Same for evaporation of watet...

Mam ek doubt h apne bola tha physical reaction vo h jo dubara use kiya jaa ske toh ye pdf m Souring of milk and burning of coke kaise hoga ye toh chemical reaction m aayega na plzz clear it mam
Man pdf me 1=melting of ice 2=vaporization of water 3= pani me suger ka ghulna.......ye sb aapne chemical btay......but quizz me ye option glt show ho rhe he
Mam...as you say that in chemical reactions hum product ko reobtain nhii kr skte...then how's... melting of ice is considered in chemical reactions. .?...bcj ice se to water bnaa skte h na to wo to physical reaction huaa. .plj clear my confusion..
Mam water se Hydrogen kko alag nahi kiya ja sakta aisa mere knowwledge me h q ki hydrogen ki jo energy produce hogi use we can't handel it plz explain this fact one time
@@99shipra kitnee bar yahi matter bolte hai dosto o physical reaction hai all you gyus known but again questioning to mam ..it's a type of disorder asking known fact also ..😀
According to your defenation of chemical reaction DECOMPOSITION reaction is not a chemical reaction. Because two substance are not involve in decomposition reaction

Melting of ice is physical Change
Thanks mam for ur hardwork & knowledge taken for us👏👏👏👏
mam ne napora banaya hai
melting of ice and

Chemical reaction me dobara waps aa b skta hai....
Hydrogen jlne pr water bnta h and heat nikalti hai.
Electrolysis se dobara hydrogen and oxygen ko alg kr skte hai.
