Question

different between flame and sphere​

Answer 1

Step-by-step explanation:

FLAME IN MICROGRAVITY is spherical owing to a lack of buoyancy and convection. In the early years of the U.S. space program, tests were conducted on unmanned missions to ascertain what would happen to a flame in a pure oxygen environment under weightless conditons

Give me thanks

Answer 2

Step-by-step explanation:

Flames are hard to understand because they are complicated. In an ordinary candle flame, thousands of chemical reactions take place. Hydrocarbon molecules from the wick are vaporized and cracked apart by heat. They combine with oxygen to produce light, heat, CO2 and water. Some of the hydrocarbon fragments form ring-shaped molecules called polycyclic aromatic hydrocarbons and, eventually, soot. Soot particles can themselves burn or simply drift away as smoke. The familiar teardrop shape of the flame is an effect caused by gravity. Hot air rises and draws fresh cool air behind it. This is called buoyancy and is what makes the flame shoot up and flicker.
