Explaining
How does fire go up?
A flame goes up because the denser surrounding air pushes it up. A flame consists of gases so hot they glow yellow, orange and red. Hot gases expand and become less dense than the surrounding air. Therefore, the flame is lighter than an equal volume of air.
Where does Adrenaline come from?
Adrenaline and Noradrenaline are two separate but related hormones and Neurotransmitters. They are produced in the medulla of the adrenal glands and in some neurons of the central nervous system. They are released into the bloodstream and serve as chemical mediators, and also convey the nerve impulses various organs.
Why is fire orange?
We see fire because energy is given off in the form of light as well as heat. Fires are commonly hydrocarbons burning in the presence of oxygen, giving rise to fine soot particles that emit yellow light when they burn at around 1,000 degrees Celsius.
