Use specific examples from Joseph Priestleys experiment to explain the relationship between what he observed and what he inferred?
Joseph Priestley's experiments with gases, particularly his work with a candle and a mouse in a sealed jar, revealed a significant relationship between observation and inference. He observed that the candle extinguished and the mouse suffocated in the jar after some time, leading him to infer that a vital substance, which he later identified as oxygen, was consumed by the flame and the mouse. This inference was further supported when he discovered that adding a plant to the jar allowed both the candle to relight and the mouse to survive, suggesting that plants produce the necessary "vital air" for combustion and respiration. Thus, Priestley's observations directly informed his understanding of the role of gases in life processes.

What did fransesco redi show in his experiment?
Francesco Redi conducted a famous experiment in the 17th century to demonstrate that maggots on decaying meat came from eggs laid by flies, not from spontaneous generation. He placed meat in three jars: one open to the air, one sealed, and one covered with gauze. The open jar attracted flies, which laid eggs and resulted in maggots, while the sealed jar remained free of maggots, and the gauze-covered jar allowed air in but prevented flies from accessing the meat. Redi's experiment helped establish the principle of biogenesis, the idea that life arises from existing life.
What is the independent variable of an experiment?

1 If you have a balloon with a fixed amount of air in a sealed jar at room temperature balloon does not fill the entire jar You place the jar in a pan of boiling The water?
As the water boils, it creates steam which increases the pressure inside the sealed jar. This increased pressure causes the air inside the balloon to expand, filling more of the jar.
What happens when you put ice cold water into a sealed jar?
The jar can not handle the temperature and compression so it cracks.
What would heating a sealed glass jar do?
Increase the pressure of the gas inside
