Answer:
As the temperature of water increases, it expands and becomes less dense. This means that warm water is less dense than cold water. On the other hand, as the salinity of water increases, the concentration of dissolved salts in the water increases. This makes the water more dense. So, if the temperature and salinity of the water are the same, the water will have the same density. However, if the temperature or salinity of the water changes, the density of the water will also change.
