Observations:
Conclusion:
1: What gas is needed for the candle to burn? Oxygen is needed for the candle to burn.
2: What happened once you inverted the test tube? Thick, white fog filled up the test tube. Also, the flame went out. It sucked up the water into the tube, too.
3: What happened to the temperature of the air inside the test tube once it was inverted over the flame? The air temperature went up because of the flame on the candle.
4: What happened to the air pressure inside the test tube? The air pressure went down because the flame was taking away the oxygen in the test tube. Outside of the test tube, the is high pressure and the high pressure puts the water down and the water went into the test tube. The high pressure air made the water go down then up into the test tube because the high pressure air is leaving the high pressure area.
- Once we put the test tube over the candle, the flame went out
- it clouded up the glass with thick, white fog
- The water got sucked into the test tube
- it filled the
