Colligative Properties
Can you keep a snowman in weather above the 32 F melting point? Not by colligative properties, and the below table will explain to you why.
Evaporation with temperature and humidity.
Water evaporates more with increasing temperature, but also evaporates less with increasing humidity. So is there any correlations where the increased temperature and increased humidity will make it evaporate the same?
Evaporation rate is proportional to the saturation vapor pressure (es(T), in kPa) at temperature T, multiplied by the dryness of the air (which is 1 - RH). RH stands for relative humidity. At 91 °F (33 °C), the saturation vapor pressure es(T) is approximately 5.0 kPa. At 20 °C, 2.34 kPa, and 30 °C, 4.24 kPa.
At 20 °C and 40% humidity, evaporation rate is similar to 30 °C and 67% humidity. At 91 °F and 59% humidity, water evaporates ~75% faster than at 68 °F and 50% humidity.
As you know, water evaporates more right after a rain, then right before. Evaporation is driven by the difference between water vapor pressure at the surface and the vapor pressure in the air. After rain, when air dries out, that difference is bigger, so faster evaporation. However, when the puddles evaporate, humidity is increased, slowing evaporation.
