Hydrophones help scientists listen to and record sounds from the ocean. Which statement best describes how ocean water affects s
ound waves? Warm water increases the speed of sound. Cold water increases the speed of sound. High water pressure decreases the speed of sound. Low water pressure increases the speed of sound.
The answer is; Warm water increases the speed of sound.
In cold water, the water molecules have lower kinetic energies than in warm water. Sounds travel faster in warm water because the molecules are more energized and the transfer of energy form one molecule to another takes shorter time because of the higher frequency of molecule collision.
Sound wave is a medium oriented wave which require some medium for travelling. While sound travels through the medium , the atoms and molecules with in the medium also start vibrating.
Thus , the higher is the rate of vibration, the faster is the conveyance of sound waves through this medium, A warm water atom and molecule exhibit high order vibration
Stimulation of a neuron causes a change in the charge inside the cell from negative to positive. This change is caused by ions, which are atoms with an electrical charge, moving across the cell. This change within the cell is consistent with the definition of an electric charge.
