Distinguish between: Dew and Frost
Answers
Answer:
It is a stage where the gas transforms into solid form by skipping the transitionary liquid phase. Frost is ice deposited on a solid surface and develops when the surface temperature passes the dew point. The colder environment allows the transformation of vapor into a solid while skipping the dew phase.
Answer:
The definition of dew can be explained by the cycle of condensation. It is the conversion of the state of matter from gas to liquid when it reaches a liquid or a solid front. Dew is a liquid formed in the form of droplets. These droplets are often seen in thin, uncovered objects in the early morning or evening.
The development of dew depends on a specific soil temperature called the dew point. At lower temperatures, the air cools and becomes less capable to hold vapor. The vapor, therefore, condenses and becomes dew. The amount of dew can be measured with a device called drosometer. This device measures the amount of dew formed per surface in a unit of time.What is frost? The definition of frost can be explained by the course of deposition. It is a stage where the gas transforms into solid form by skipping the transitionary liquid phase. Frost is ice deposited on a solid surface and develops when the surface temperature passes the dew point. The colder environment allows the transformation of vapor into a solid while skipping the dew phase. There are several types of frost.
The radiation frost appears in icy crystalline forms and occurs on the ground or on an uncovered facade. This type also forms in refrigerator-freezers. An advection frost (or wind frost) appears as an ice peak and develops when cold winds blow against tree branches, pole surfaces, and other exposed areas window frost types can occur after a window pane has been subjected to cold outside air and foggy inside air. This form is common in places with generally cold climates. Rime frost is a frost that resembles a layer of ice. It is triggered by cold, windy weather conditions.
Frost, in most forms, is considered a threat. It makes roads slippery and wet, putting motorists and commuters at risk. It is also a threat to agriculture because it destroys crops that do not grow under frost conditions. In order to prevent plant cells from freezing, agriculturists spray them with non-freezing bacteria to mitigate frost damage. Another method is to make a selective inverted sink. In this method, a large fan is used to draw moist, icy air away from the crops by pushing it up a chimney
