Gasses and climate change

Combustion
Hypothesis: The combustion will produce flame and soot but nothing else.
The combustion created a sound like a whoosh and flames flew into and out of the bottle.
The human race is creating chemicals that a not supposed to be int eh atmosphere by using combustion.

CO2
Hypothesis: The flame will create a sound and soot.
The CO2 killed the flame.


Hydrogen
Hypothesis: There will be no flame.
The chemical reaction from Zinc and the acid was fizzy.
The flame created a boom and a flame that eventually dissipated and bubbled the liquid.
There are many fuel sources that the humans do not use like tidal power and geothermal energy, these are powerful and could work as renewable resources, also scientists believe that in 2025 the world will be at Peak Oil which means that almost half of the Earth's oil that can be extracted will be extracted.


Air Pressure
Hypothesis: When she puts the can into the ice bath, the can and vapor will freeze because of the change in air pressure.
When she put the can into the ice bath nothing special happened.
Hypothesis 2: When she puts the can that is sideways is the vapor will turn to ice.
The rapid change in air pressure crushed the can. The inverted can also took in some water and replaced the vapor in the can.
The air pressure is changing and affecting temperatures and other weather like increases of rain in Scotland, reduced rain in Spain, and a drop in the number of cold snaps in France.
Winters will be warmer, wetter, and windier in Europe due to changes in air pressure.
The winters will get milder in Canada and the U.S.
