That cool air hitting the warm iron results in almost instant

Generally, warm and moist air hitting a cool surface is what cuases
condensation on the cool object. Cool air hitting a warm surface does
NOT give condensation.

So, when it is zero outside and 70 inside my house with 70% humidity,
the wet stuff on my windows (inside) is NOT condensation???

Han is correct.

What you describe is the result of the warmer air inside the building
hitting the colder surface of a cold window, not 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. 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.

If it real cold, what about frost?
