Internal styes are infections of the meibomian sebaceous glands lining the inside of the eyelids. They also cause a red bump underneath the lid with only generalized redness and swelling visible on the outside.
Now frost is a covering of ice crystals on the surface produced by the depositing of water vapor to a surface cooler than 0Â° C (32Â° F). The deposition occurs when the temperature of the surface falls below the frost point.Similarly, dew forms when the air or surface temperature falls below the dew point temperature.herefore, frost is not frozen dew.). Thus, if the temperature on the ground or an object such as a bush or a car windshield near the ground falls below the frost point, frost crystals may form. But the measured  surface temperature  may still be above freezing.
The most obvious is temperature. If the air temperature is above 32Â°F snow and ice will start to melt, at or below 32Â° and it will remain frozen. Think about a popsicleâ¦ inside the freezer it stays frozen, outside it starts to melt. The amount of sunshine plays a big factor.
