Warm water is less dense than cold water and has lower salinity than cold water.

Explanation:

When the temperature of water increases the freedom movement of molecules increases and they expand. Hence the space between the molecules increases thereby causing the liquid to occupy more volume. Density is the ratio of mass and volume which means an increase in volume will decrease the density of a liquid.

Thus an increase in temperature has a negative impact on density and the density decreases. Salinity tends to increase with density. Thus temperature has a negative impact on salinity as well. When temperature increases salinity decreases.

this website is for anybody really not just for girls just saying, also while a lot of males are mean and you know there are the few who are kind and then there's the nice-guys but then theirs also guys like me who are shy we don't get out much because there are people like you who exist who would most likely punch a guy in the face so next time just think about things before you post them to a website where guys and girls can see your question.
