The Impact of Humidity on Paint Drying Time
A team of physicists at The University of Edinburgh has conducted an experiment to validate a theory explaining why paint dries at the same rate regardless of humidity levels. The researchers found that evaporation rates remained constant for approximately three hours, regardless of humidity levels. This supports the theory that a polarization layer forms during evaporation, inhibiting further drying. However, at humidity levels above 80%, evaporation did slow down, likely due to other factors. The study could have implications for understanding respiratory droplets and their behavior.
