Temperature and salinity changes the density of water.
<h3>Effect of Temperature and salinity on water</h3>
Temperature and salinity directly affect density of water. Water that low temperature is more denser than water that has high temperature while on the other hand, Freshwater which has no salt is less denser than seawater which has more salt concentration so we can conclude that temperature and salinity changes the density of water.
