Kon kon yahan pe apne half yearly ke liye 😂

[Shravani__]

Kon kon vacation mai dekh raha hai ?? legends aapni attendence lagao bhai 😅😅

00:03 The chapter discusses matter classification based on physical and chemical properties.
02:51 Matter around us can be impure even if it seems complete
07:48 Gold is an element and water is a compound
10:11 Matter classification: elements and compounds
15:08 Metals have unique properties
17:23 Metals and non-metals have distinct properties.
22:24 Compounds are substances made up of multiple elements chemically combined.
24:24 Compounds are chemically combined in fixed proportions.
28:57 Matter can be classified as homogeneous or heterogeneous.
30:48 Matter has homogeneous and heterogeneous compositions.
34:30 Understanding homogeneous and heterogeneous mixtures
36:37 Matter can exist in different states and solutions
41:22 Matter can be separated based on the properties of its constituents

[nandlalmeena]

Because of her explanation I think Chemistry is quite easy 😅❤❤ Thank you ❤

[prabhatsingh]

Legends best of luck for tomorrow exam 😂

[kewalsharma]

The AnSwer of queStion iS
(A) = concentration of common Salt = 20 /550 ×100 =3.636...
(B) = Concentration of glucoSe =30/550 ×100 =

[Ishan..]

The way She explained can't be describe in words ❤️

[Shriti-qn]

52:45 😆"they have no dum, they are not singham" that's why I love physics wallah 😂Their teaching is so interesting ❤

[exphubmotivation-bfit]

Kon kon Manta hai ki school mein padhai nahi hoti hai 😂

[shouryagupta]

To be honest, me and friends only watches your videos to overcome our doubts. You're a brilliant teacher 😊

[trilokrathore]

Mam please 🙏🏼 come in our school 🏫 to teach us 🥰.
Because you are chemistry queen 🏆🤩.

[parthsarthyrai]

I got full marks in chemistry after this :25/25! THANK YOU SO MUCH MA'AM!🙂

Edit- Tysm guys for 106 Likes~!

Q: 1. Coffee/ Chai = Homogeneous mixture
2. Cornflakes = Heterogeneous mixture.
Q: A beaker has concentrated solution because concentration of solutions depends upon the amount of solute present in the solvent.
Q. a. Concentration of glucose - 30/550 ×100 = 60/11
= 5.6%
b. Concentration of common salt - 20/550×100 = 40/11
= 3.6%
Q: burning of candle = is both [ physical and chemical change ]

[anshu]

We are going to class 10th I am so excited mam💥💥🙂🤘

Thanks for likes friends

[AnujAgarwalla]

Kon 2024 ke unit test ke liye aaya hai... Full marks button 👆

[anmol]

1:05:51 Concentration of glucose in solution =5.45%(60/11)
Concentration of salt in solution=3.63%(40/11)

Legends are watching it one day before exam😂🤣
