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.
The heaviest coatings of frost usually do not occur at the coldest temperatures because very cold air can not hold very much water vapor. Instead, thick deposits of frost usually occur when the air temperature is close to 32 deg.F (0 deg.he heaviest coatings of frost usually do not occur at the coldest temperatures because very cold air can not hold very much water vapor.

Frost forms on objects when water vapor in the air condenses close to or on the ground. Farmers have developed ways of predicting and preventing the formation of frost on crops. They take into account different aspects of weather such as humidity, wind, clouds and the dew point to determine if there will be a frost.
