When taken out of the freezer, the temperature of the sausages is likely less than 0 degrees C.
When water vapour in the surrounding air comes into contact with the surface of the wrapping, heat energy is transferred from the water vapour on the wrapper, causing the water vapour to decrease in temperature. This happens until the temperature of the water vapour reaches 0 degrees C which is the freezing point of water. The white solid formed is the frozen water vapour
