Question

Jessie has never seen snow, but today the weather conditions may be just right! He knows the temperature on the Fahrenheit thermometer must be _______ degrees or lower for him to see his first snow fall.

A) 32 o
B) 20 o
C) -10 0
D) -32 0

Answer 1

The answer is 32° F, because water freezes at this temperature under normal pressures, and snow is water vapor frozen into ice crystals.




N.b., it usually needs to be a little bit colder to have snow, but this is around the maximum (although I've seen snow around 38° F before).
