If an area is in the 50+ dBZ range, what atmospheric pressure conditions could the area be experiencing?
monitta

The atmospheric pressure conditions for a 50+ dBZ range differs from small to heavy hails.

Explanation:

dBZ refers to decibel relative to Z used in weather radar most of the times, in order to compare the reflection factor (Z) of a weather radar signal reflected off a remote object  to the return of a droplet of rain with a diameter of 1 mm.

dBZ is a logarithmic dimensionless technical unit, at 55 dBZ and above, most storms have hail which can throw off the rainfall rate because hail has a higher reflection.

Generally above 50 dBZ range the intensity varies accordingly for every 5 points. Such as small hail to moderate hail and from moderate to heavy hail.

Therefore the atmospheric pressure conditions differs from rains to hails.

Nataly_w [17]

The answer is benedict’s reagent.  Benedict’s test is used to detect reducing sugars in solution when heated. The color change occurs from clear blue to a brick-red precipitate in the presence of the reducing sugars. The cupric compounds in the benedicts reagent react with the reducing sugars (enediols) produced from heating of the reducing sugars in the presence of an alkali. Benedict's reagent is comprised of a mixture of sodium citrate, sodium carbonate, and copper(II) sulfate pentahydrate.
