Question

LPG gas fuel forms blue color on combustion but other other materials show orangish yellow colour, why? give a reasoned answer​

Answer 1

Answer:

Ok I'll answer this question

Explanation:

The LPG (propane) gas flame colour appears blue because complete combustion creates enough energy to excite and ionize the gas molecules in the flame. The exception is a gas fireplace flame color being yellow, for a more realistic look.
