Why do the water droplets form on the window?

Water droplets form on a window due to condensation, which occurs when warm, moist air comes into contact with the cooler surface of the glass. As the air cools, its capacity to hold water vapor decreases, causing the moisture to condense into tiny droplets. This process is more pronounced in humid conditions or when there's a significant temperature difference between the air inside and outside the window. The droplets collect and can create a visible layer of water on the glass.
