State your claim and use evidence to support

it. For each piece of evidence you use, explain

how the evidence supports your claim or

refutes another claim. Remember to explain

what happened at both the macro and

molecular scale.


Claim 1: there is frozen water in tank 2, which is blocking some of the oxygen from going into tank 3

Claim 2: some of the liquid oxygen evaporated in tank 3.

Claim 3: some of the oxygen didn’t condense in tank 2
