How is a glass jar made?
A glass jar is made by first heating sand, soda ash, and limestone to very high temperatures to form molten glass. This molten glass is then formed into the desired shape by blowing, molding, or pressing it into a mold. Finally, the glass is cooled slowly to anneal it and make it strong for everyday use.
Why would a candle burn longer in the open other than in a glass jar?
If the glass jar is sealed, there is a limited amount of oxygen within it. Fire uses oxygen to stay alive. Once it uses up the limited amount of oxygen in the glass jar, it can no longer sustain flame. However, in the open, there is a theoretically unlimited amount of oxygen.
What would happen if you poured boiling water into a jar?
Glass is a great conductor of heat but it doesn't hold it long. If you were to stick 212o (Fahrenheit) water into a glass jar it would begin bringing the glass jar to the same temperature as the water on the inside very quickly (equilibrium). It also begins building pressure, so If a lid is on the jar it could potentially explode the jar sending boiling liquid and glass shards everywhere.
Why is a tightened lid on jar easier to remove when heated?
Heating the jar causes the air inside to expand, increasing the pressure. This added pressure helps to loosen the lid by pushing it away from the jar, making it easier to remove. Additionally, heating can also help to soften any sticky substances that may be causing the lid to stick.

If a candle was bigger than a plant would the candle stay lit longer if they were both sealed in a glass jar?
Yes, a larger candle would likely stay lit longer than a plant if both were sealed in a glass jar because candles are designed to burn for extended periods of time, while plants require specific environmental conditions to survive. The larger candle would have more fuel to sustain the flame compared to a plant.
