Gases and Climate Change

Fuel ignites, we have "fuel", and we have a lighter. We are spreading the rubbing alcohol around the inside of the bottle, and the lights will go off. If we light the rubbing alcohol, it will catch on fire and light up.

The inside of the bottle had purple fire for a split second, then shot off the table. It made a huge wooshing noise. If we had left extra rubbing alcohol in the bottle, it would have burned for much longer. Just coating the inside resulted in a quick combustion process.

Combustion processes hurt the atmosphere by releasing gases in larg quantities than naturally appear. They also make the greenhouse effect grow worse. In the past decade or so, certain gases produced through combustion processes have risen to extreme levels.


When we hold the CO2 gas meets the flame, I think it will smother the flame.

The gas met the flame, and the flame went out. It was extremely simple. The CO2 is a heavy compound, smothers the flame, and does not have enough oxygen to support the fire.

Just as Vitamin D is essential to human life, CO2 is essential to environmental life. However, just as the vitamin can be toxic in a large quantity, too much CO2 is damaging to the environment.


If the hydrogen is exposed to flame, it will ignite.

The hydrogen was escaping visibly, in a whitish gas. It was an immediate reaction, and the hydrchloric acid was bubbling.the beaker was hot. When exposed to flame, the hydrogen gas made a loud, sudden pop like fireworks do, and it ignited. It burned until the reaction between the acid and the zinc slowed.

Biofuels are actually less efficient and more damaging to the atmosphere through the process of obtaining it than regular fuel.

Peak oil is when the planet's original supply of oil is halfway depleted. Many scientists believe it is already reached or will be by 2025.


Air pressure:
When the hot water vapor is cooled, it will drop to the bottom into water again.

Nothing happened that was visible or able to be heard.

The hot air will make the can bulge because warm air rises and cold air sinks.

The can crushed itself completely, like a vacuum sucked all the air out of it. It was an immediate reaction. There was a pop because the can crushed.
