1:20:20 Answer: Burning of Candle is a Chemical change. As new substance is formed while the candle burns.
It's physical change
Finally chapter 2 complete successfuly 😊🎉❤

Can you please tell me the steps
Thank you so much ma'am ❣️✨ you're really a wonderful teacher ❤
She is the teacher that every student needs...just look at her explanation how she explains how she talk..❤
Best chemistry teacher in the world thank you mam ❤
Mam,Your teaching style is mind-blowing
34:39 Answer: Chai/Tea is a Homogeneous Mixture as substances or compounds are mixed together completely.
While, Cornflakes + Milk is a Heterogeneous Mixture as substances can be distinguished from one another.

Preparing for CDS 2026 exam after 12th . Clearing basics . Humanities student here . Kabhi science math hua nahi. Mujhe lagta tha mujh mein koi kami thi , par abb itne acche teachers se maths , science padhne par pattaa chala , acche teachers milna bhi kitna important hai.
52:45 😆"they have no dum, they are not singham" that's why I love physics wallah 😂Their teaching is so interesting ❤
U really made it easy to understand the chapter the way u teaches the example u give to understand is really great thnx 💫💫💫
Mass Percent Of Glucose = 5.45 and Mass Percent of Common Salt = 3.63
buring of candle is both physical and cemical change
in which melting is a physical change and in which buring of wick is a chemical change .

1:05:51 Concentration of glucose in solution =5.45%
Concentration of salt in solution=3.63%
salt wala galat hai
bro your answer is correct but according to Google there was a bar in 45
@@adarshpatidar6706 yeah 45 is coming continuously so there will be bar on 45 in 5.45%
@@kirinaved_ it is right, please check your answer
OK and what about salt there was a 3.636363 and 64
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 ]

i) Non-metals are bad conductor of heat and electricity.
Q.) If Non-metals are bad conductor of heat than why wood catches fire ?

Concentration of glucose----
Solution = solvent+solute
=550g
Mass of glucose/mass of solution
=30/550×100
=5.45
ii) mass of common salt/mass of solution ×100
20/550×100
=3.63
Hi Ma'am
@sabbirsaiyad240130/550 me 0 ko kaat denge aur fir 3 ko 100 se multiply kr denge 300 aane pr usko 55 se divide kr denge fir aa jyega 5.45%

a) Glucose = 5.4545...%
b) Salt Solution = 3.6363...%
