Question
There are several characteristics that make a "perfect flame". Indicate which of these characteristics are included. See the General Laboratory Equipment and Procedures for a discussion. The perfect flame may flicker and occasionally have flames shooting out of the bottom of the barrel. The perfect flame may have a bit of smoke escaping. The perfect flame is adjusted at the bottom know for height because the gas valve at the bench top is in the full on position. The perfect flame is double coned; one inner and one outer. The perfect flame color can be adjusted by twisting the barrel. The perfect flame has a yellow color. The perfect flame has a blue color. The perfect flame has about 1 ft tall.Explanation / Answer
Answer :-
Explanation
Color
A perfect flame consists of a narrow plume of pale blue flame. A flame that contains any tint of orange color means that either not enough gas is flowing through the burner or not enough air is being mixed with the gas. An orange flame will not be hot enough for most laboratory purposes. A flame with a bright blue triangle within a pale blue flame is too hot for most experiments, although it may be desirable for specific tasks requiring a great deal of heat.
Steadiness
The flame should be very steady, with no flickering or fluttering. A flame that flickers or flutters may have too much air mixed with the gas and is in danger of going out. The flame should also emerge directly from the nozzle of the burner. If there is a visible space between the nozzle and the bottom of the visible flame, there is too much air in the mixture. A steady flame provides the most uniform level of heat and allows for steady and predictable heating.
