Gases and climate change

Combustion
Hypothesis: If the fire turns blue then some blake soot will come out.
Observation: ONce the flame reached the gas the flame turned blue the bottle flew off the table with a loud WHOOSH and left a little soot on the floor.
I learned that the things that we think are harmless are actually pretty dangerous to our enviroment and causes glaciers to melt and melt and melt causing our sea levels to rise and rise and rise to up to an inch per year.

C02
Hypothesis: IF the gas gets free then the flame will get bigger for a little than start dieng down.
Observation: When the gas Surrounded the air the flames died out really quickly.

Hydrogen gas:
Hypothesis : that when the flame touches the gas the flame will expand really quick but then disappear.
Observation: When the zinc when touched with the hydrochloric acid it started bubbling and producing gas and when the flame touched the gas it light it on fire and continued to be on fire for about 20 seconds and then died down. when it was down the beaker was hot.

Air pressure
 Hypothesis: If the can has enough water vapor then the water vapor will come out fast.
Observation: The water vapor didn't come out fast it was just normal like nothing happened.

Hypothesis If the can is placed upside down then it will pop up out of the water.
Observation: When the can touched the water when it was up side down it sucked itself in and crushed itself.

That the air pressure can affect our weather big time and If the air pressure dropped then it all depends where you live there could be warmer or colder winters and it could change so the weather would be more dry or humid.
