Nitrogen--- -196 Degree Celsius
Argon--- -186 Degree Celsius
Oxygen--- -183 Degree Celsius
A mixture of oxygen, nitrogen and argon at -200 Degree Celsius is allowed to warm up grudually by 16 Degree Celsius. Which of the substances will still be in the liquid state?
The answer is oxygen only.
But why is oxygen only? I don't understand...Can anyone explain this question to me? Thanks a lot. =)

after heating you will be at 200-16= -184°C
and at that temperature oxygen is still liquid (by just 1°C) while the other 2 gases have boiled out.

After warming you reached -184 degree celcius. At this temp. Oxygen is still liquid and the others are boiled out as their b.p's are greater than -184 degrees

Oxygen requires more heat. If you warm it up by 16degrees it would be at -184.
