Conclusion:
1. Oxygen
2. The fire blew out, this happened because the wind of the test tube coming down blew it out. Also, the water of the pan went about halfway up the test tube, I think that this happened because we put high pressure which cause the water to rise.
3. It cooled down, because the high pressure caused the low pressure air to exit the test tube.
4. It got dense.
