Answer 1

Priestley observed that a burning candle would get extinguished in a closed bell jar.

In August 1771, Joseph Priestley conducted another set of experiments where he placed a mint plant into a transparent closed space with a burning candle that eventually burned out the air until it soon went out.

Priestly discovered that the relit candle burned perfectly well in the air that previously would not support it.
