Why is the liquid oxygen machine producing less liquid oxygen than normal?
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
