Tanya and Riya are best friends. One evening Tanya went to Riya’s house and found her working in the kitchen. She saw that the burner was emitting yellow flame and a black soot was getting deposited on the bottom of the cooking vessel. She advised Riya to put off the gas and clean the holes of the burner. After cleaning the holes they found that the burner was now emitting clean blue flame.
(i) Why was the burner emitting yellow flame?
(ii) What was the purpose of cleaning the holes of the burner?
(iii) What value is expressed by Tanya?

i) The burner was not getting enough air for complete combustion of the gas.
ii) The purpose of cleaning the holes of the burner was toadjust the burner’s air shutter to admit more air. So that it could burn with complete combustion.
iii) Tanya is Sensitive and have keen sense of observation.
Hope it helps:)
