Combustion- Hypothesis: When we light the rubbing alcohol. it will give off polluting smokish-gas. What Happened: The alcohol inside of the bottle ignited and it blasted off with a whooshing sound and filled with fire.
Combustion causes climate change because it adds to the green house gases, causing the world to heat up.
CO2 Gas- Hypothesis: I think that this gas willl ignite. Well, it didn't ignite. It just put the fire out. This happened because the CO2 deprived the fire of oxygen, which is vital for a flame to burn. It is argued that CO2 in the ocean is being released because of evaporation and rising climates. And since CO2 is a green house gas, it is causing the climate to get hotter and hotter.
Hydrogen Gas- Hypothesis: I think that the Hydrogen will ignite like the first expiriment, because it is used as fuel. My hypothesis was curect, the H burned when fire was introduced.
Fossil fuel is declining so that instead of using one barrel of oil and getting a hundred, you use 50 barrels of oil, and only get 50 back. This is called net energy.
Ocean power has to do with the movement of waves going up and down, therefore creating electricity.
Biofuels are like fossil fuels, but it takes more fossil fuel to create energy equal to biofuels.
Solar electricity is one of the most popular sources of renewable energy. All of the power on the earth, solar power is the most common. Wind power is one of the fastest growing energy sectors. It is very efficient energy source.
Geothermal energy is energy created at the Earth's core.
Air Pressure-Hypothesis: The gas will turn to ice crystals. Well, nothing happened at all. Now we are going to do a second experiment. Hypothesis: The can is going to blast into the air when we place it in the ice water upside-down. That didn't happen either. Instead, the can kind of went *plink* and crushed into itself.
