Why do copper pipes sweat?

Pipe sweating occurs because cold air holds less water vapor than warm air. When a cold pipe touches the hot, moist air around it, the temperature around the pipe drops and the air reaches its dew point. This causes the water vapor in the air to become a liquid and collect on the side of the pipe.
