What type of water would never freeze?

Explanation:

As a result, you can cool very pure water well below zero degrees Celsius without it freezing. Water in this condition is called "supercooled". At standard pressure, pure water can be supercooled to as low as about -40 degrees Celsius. Supercooled water is kept from freezing only by the lack of nucleation centers.

i would say

80cm/s.

24cm/s.

53.3cm/s.
