Think for Yourself... |
 |
What is the flame?
|
|
Why doesn’t
the whole bag of methane set alight at once?
|
|
When the jar is
placed over the top, why does the flame go out with
plenty of methane still left?
|
|
Why does the condensation
form on the sides of the jar but not at the top?
|
|
|
|
Suggest what substance
the condensation might be, and explain your reasoning.
|
|
Some people might
say that the condensation could be from water that was
already in the air. What is the argument against this?
|
|
There must be at least one other
substance formed: why?
|
|
In fact, there
is just one new substance. Why can’t we see it
and what might it be?
|
|
How could we test
for this other new substance?
