Question

As the temperature of seawater increases from 15oc to 20oc, sound velocity through the seawater.

Answer 1

Below

Step-by-step explanation:

The speed of sound INCREASES with increase temp in seawater( and air )

For seawater the speed INCREASE Is about 4.5 m/s per degree C

or 22.5 m/s faster when the temp is 20 °C vs 15° C
