Question

Why.Speed of ultrasonics decrease at high temperatures in water?

Answer 1

Answer:

.

Explanation:

i may explain this partially, but try to understand, okay so consider a submarine or a ship having ultrasonic tech to detect the depth of a ocean, if an volcanic eruption happens at the bed rock of the ocean the water obviously gets heated up, so we know that sound travels at the rate of 350m/s, so when the sound travels, it gets disturbed/scattered by the high kinetic energy in the water as it is on high temp, so as the water has high K.E the sounds waves gets scattered making it to decrease its velocity !
