and lets call ' steam ' water vapor above 100C that is condensing.
you open your CSO at 350 F Steam-Bake : you get some superheated
water vapor , hopefully no in your face.
water vapor can condense below 100 C : Mist.fog etc
and for completeness sake :
water has a ' triple point '
where each phase ( liquid , vapor , solid )
is in equilibrium .
not often useful in cooking.
