yea they just "warm the glass" giving it their energy, thus slowing down and eventually condensating because they've lost so much energy (cold stuff absorbs heat from the warm stuff)

on the contrary if you boil the water like madman you're giving water molecules so much energy it flies away as steam :)

Yea, from our huge perspective it's a bit strange to think about. Heating a pan means you're giving kinetic energy to the pan itself, the pan molecules are then smashing into the water molecules
