A goldsmith uses the blue zone of the candle cause it os the most hottest part and melts the gold and silver easily
HW : a goldsmith use the outermost layer of a candle flame to melt Golden and silver because it is the hottest zone has a very high temperature and complete combustion take place in the zone the flame
It's Upsc question
8:19 , outermost layer , because it is the hottest layer and to melt gold and silver high temperature should be used . Thus the hottest outermost layer is used for melting gold and silver
Thank you for the session Kriti mam❤ it's really helped me to understand the structure of flame thank you ma'am hopefully I think to see you soon
The goldsmiths use outermost zone of candle flame because it the hottest part of candle and it can easily melt silver and gold
A goldsmith uses the outer zone of a candle flame to melt gold and silver because it is the hottest zone, has a very high temperature and complete combustion takes place in the outermost zone of the flame.
H.W
A Goldsmith uses the outermost region os a flame as it is the hottest of all. It has a temperature of about 1400 degree celcius which can easily melt gold.
Thank you
Outer zone or non- luminous zone bcz it's hottest part of flame and as gold is a metal so it needs high temperature...
Very well elaborated.
For melting gold Smith outer zone is used because it's hottest zone and in hottest zone the gold Smith can melt fast
H.W : Goldsmiths use the outermost zone of a flame to melt gold and silver. This is because:
It's the hottest part of the flame
due to its heat it is able to melt the metals like gold and silver which have high melting points
😆Thank you for the session Kriti ma'am! It really helped me understand the structure of a flame better.hope to see you soon ma'am👋
Mam thanx for bringing this seision this channel is realy amazing
Hats off to u mam ❤❤❤❤❤❤❤❤
What about blue zone?????
Mam can you tell us about anthe exam result please 🙏
H.W ANS-
A goldsmith uses the uppermost zone for melting gold because it is the hottest zone in a flame.
THANK YOU SO MUCH MAM FOR THE AMAZING SESSION
Fuel ,ignition tem,oxygen
The ans for the hw question is the outer most layer....
The non luminous zone because its temp. is hottest one and it takes complete combustion
Outer most zone as it is the hottest zone of candle flame 🔥🔥
Home work answer :- Outer Zone or Non Luminous Zone
H. W ans
A goldsmith uses the non luminous part of the flame as the temperature of this part is around 1300°c because it is sufficient to melt the gold at specific points and also helps to give proper shape to the gold ornaments.
Maam the session was amazing. Maam i request to bring videos on fuels and their types.
Please class 7 history tribes, nomads and settled communities
i am in 6th grade i want to join the sessions can you guide me
The answer is : outer zone because it is the hottest zone among the three zones of flame
Hi
Bey
A goldsmith uses the outermost zone of a flame also called outer zone or "primary combustion zone," is used to melt gold and other metals. This zone is the hottest part of the flame and contains the highest concentration of heat and energy. Gold melts at a relatively high temperature of around 1,948 degrees Fahrenheit (1,064 degrees Celsius), and the intense heat of the inner flame zone provides the necessary temperature to melt the metal.
Mam
Outermost blue zone
The goldsmith uses the outermost zone which is the non luminous zone as it is the hottest zone in a candle flame.
This is premier
outer because it is the hottest
