comment What are conditions for the existence of a critical value (for a phase transition)?
remember that in this picture the scaling of the axis is not constrained: in reality the Pressure axis is much much longer...

comment How do electrical devices suck electricity?
but then again you are wrong: if U_{NA}=220V=I*R and U'_{JEU}=110V=I'*R then I' = I/2, and P'=U'*I'=P/4! so jewropean outlets can push 4 times more energy through the same kettle resistor than in Northern States of America
