What would happen on a humild day. if you took an empty metal cup out of A freezer and put on a napkin?

On a humid day, taking an empty metal cup out of a freezer and placing it on a napkin would cause condensation to form on the exterior of the cup. The cold metal would cool the air around it, leading moisture in the humid air to condense into water droplets. This moisture would then soak into the napkin, potentially making it damp. The overall effect would be a visible accumulation of water on the cup and surrounding napkin, illustrating the principles of condensation.
