Frost typically has a density less than 0.1 g/cm3 [1]. Thicknesses are typically less than a few millimeters. Though frost crystals can be easily crushed and “polished,” frost often cannot be removed from surfaces without the use of heat, chemicals, or mechanical scraping. The cohesion of frost is weak, but its adhesion is strong. Frost is often prevented using covers, or by spraying a freezing point depressant, such as glycol, on a surface before the frost forms. [2]
