Use specific examples from Joseph Priestley’s experiment to explain the relationship between what he observed and what he inferred.

Priestly observed that adding a plant to the jar caused the candle to stay lit longer.

Priestly himself inferred that plants gave off oxygen during photosynthesis, it provided the oxygen that was needed for the candle to be able to burn.

Joseph Priestly observed that a candle alone in a jar did not stay lit for long and eventually went out and that when he added a plant to the jar, it caused the candle to stay lit longer and the plant to stay alive longer. Priestly then inferred that plants give off oxygen during photosynthesis, providing the oxygen needed for the candle to burn and that the burning candle gave off carbon dioxide, which was used by the plant.
