(1 point)
Responses
Both temperature and salinity decrease the speed of sound in water.
Both temperature and salinity decrease the speed of sound in water.
The speed of sound increases as the temperature of water increases.
The speed of sound increases as the temperature of water increases.
The speed of sound increases as the salinity of water decreases.
The speed of sound increases as the salinity of water decreases.
At 80°C, the speed of sound in freshwater and seawater will be the same.
1 answer
The correct statement about the speed of sound in freshwater and in seawater is:
The speed of sound increases as the temperature of water increases.
This is supported by the data in the table, which shows that as the temperature increases from 0°C to 30°C, the speed of sound in both freshwater and seawater also increases. The other statements are not accurate based on the provided information.
