What you describe is the result of the warmer air inside the

reverse.

Condensation generally happens when warm, moisture laden air hits a
cooler service.

When is the last time you saw condensation forming on a mug of hot
coffee on a cold day?



It is relative.

Already stated in subsequent post prior to yours.

If it is warmer on the inside than out, the condensation
will be on the inside of the window. If the reverse is true it would
be on the outside of the window. You can see this when you have a hot
humid day and have the air conditioner very cold.

Read again what I said ... nothing in your quote above changes what I
stated in the least.

If it real cold, what about frost?

Frost has nothing to do with condensation. AAMOF, if the conditions
are right for condensation, you won't normally see "frost":

Karl is right. Just like little frozen ice puddles will disappear on a
clear day without any evidence of liquid water (it's called sublimation),
a very cold object can acquire little ice crystals (frost) when the
surrounding air is moist enough. See again "dew-point".
