Why does wood initially burn with a flame and later only grows without a flame?
When wood burns initially, it releases flammable gases like hydrogen and methane that ignite and produce a flame. As the fire consumes these gases, the remaining wood chars and forms charcoal, which burns without producing visible flames because it requires a higher temperature to combust. This process is known as smoldering.
Why is it important to do the experiment with the blue flame first?
Doing the experiment with the blue flame first is important because it helps establish a baseline understanding of how a clean flame behaves and what to expect as a reference point. This can help in identifying anomalies or deviations when conducting experiments with other flames later on.
Why did scientists think that lime was a element?
Scientists initially thought lime was an element because it could not be decomposed into simpler substances by chemical means. It was later discovered that lime is actually a compound of calcium and oxygen, known as calcium oxide.
Who was the founder of boron?
The element boron was discovered and isolated by Sir Humphry Davy and Joseph Louis Gay-Lussac in 1808. Initially, Davy thought the substance was a metal, but later studies revealed its non-metallic properties.
When was propane used first?

Is there a real difference between flame-retardant and inflammable bedding?
There is a real difference. A flame-retardant bedding has filler that is not flame resistant, but the outer later is flame resistant. As for inflammable bedding, both the filler and the outer layer are both flame resistant.
What did the Phoenicians write with?
Initially a chisel, then a stylus, later a quill pen.
What the later refinement added to the design which allowed the energy of the flame to be altered?
The later refinement added a control mechanism, such as a valve or knob, which allowed the user to adjust the flow of fuel to the flame. By controlling the fuel flow, the user could increase or decrease the size and intensity of the flame, thus altering the energy output of the flame.
What did the Nazis initially do with the Jews?
They limited them and put rules on them, and later moved them to ghettos.
Who made Demeters's daughter with her?
Initially Persephone didn't have a father but later they attributed it to Zeus.

i don't no ask again later..... good bye person
