Gasses and climate change

the alcohol will combust, and it will inflate the bottle, when (teacher) puts the lighter inside, and lights it.
what happened: i was sort of right, it inflated the bottle, made a large "WSHHHHHHH" sound, and it flew across the room.
combustion and other gasses affect the planet in ways that are good, and ways that aren't so good, they trap heat in, and that can be both good and bad. when heat is trapped in the icy area start to melt, and the hot areas become even more hot, but the cold areas warm up, and some uninhabitable-due-to-extreme-cold areas become habitable.

I think that when (teacher) introduces the gas to the catalyst, it will ignite, but not provide enough thrust to make the beaker fly.

What happened: the trapped gas did exactly the opposite of combusting, it put the candles out.

Co2 has a negative effect on the environment, and a positive one. it helps to fuel trees, plants, and other plant based organisms, but it has a negative effect and is released into the atmosphere when that thing dies.

i think that when it is introduced to the flames, that it will not combust, and it will float to the ceiling harmlessly.

What happened: it did just the opposite... again.... once the zinc was introduced it started to produce gas, and when lit it burned until the fuel source(the gas) ran out.

Pros: renewable, energy storable. renewable, long lasting, no emissions. The general decline of available oil. renewable

Cons: still releases greenhouse gasses. Costly installing fee. The lack of fallback fossil fuels. more costly than hydro electricity


I think that the can might expand if covered, and it will flow out of the can.
What happened: nothing at all, as (teacher) moved the can from the hotplate into the ice bin, nothing happened.
I think that the can will either expand, or the steam will flow out of the can through the can.
What happened: my second prediction was right. the steam flew out of the can, and the lack of air in it crushed it.
