Question

At what temperature does sea ice form in the polar oceans?

A.
0°C
B.
-0.5°C
C.
-1.9°C
D.
-2.4°C
E.
-32°C

Answer 1

C. -1.9C Because the freezing temperature of salt water is lower than fresh water.

Answer 2

The answer is: C. -1.9 °.

Step-by-step explanation:

As we increase the salt content of the water, its freezing point decreases, so that for a water with a salinity of between 30 and 35 psu, such as that usually found in the Arctic Ocean, it turns out that it should cool down to - 1.8 ° C to freeze.

The answer is: C. -1.9 °.
