Jun 16, 2020 · Also asked, does water have to be 100 degrees to evaporate? If the relative humidity is less than 100%, water will evaporate into the air, becoming water vapor. This means that at 100°C, you can have pure water vapor at atmospheric pressure. This is why water boils at 100°C at sea level—a bubble of steam can form below the surface of the water.
