To recreate Priestly's experiment, which of the following are required along with a bell jar?

• A. Candle
• B. Mouse
• C. Plant
• D. All of the above

Answer 1

The correct option is D All of the above

To recreate the classic bell jar experiment, we need a mouse, a plant and a candle inside the bell jar.
Priestly when perofming the experiment observed that, a lit candle placed inside a jar got extinguised quickly.
However is a living plant was placed inside the bell jar, the candle would stay lit for longer.
He also found that a mouse would stay alive for a longer time when placed inside a bell jar along with a living plant.
