What is the effect of temperature and salinity on the density of water?

Answer 1

This is a simple one.

# Density is mass divided by volume. # Heat increase causes increase in volume. # Therefore, as mass is constant and volume is increasing, the density will drop.

Hope that helps!

Answer 2

The effect of temperature is that the warm water is denser than colder water, since the molecules are spread out so the warm water sinks to the bottom. The affect of salinity is that since the water is salanatized it sinks to the bottom while the fresh water floats (due to the amount of salinity).

Answer 3

When the temperature of a liquid changes, its density also changes. ALMOST but not quite everywhere
in nature, rising temperature of a liquid means that it expands ... its density decreases.

But there is one weird substance that violates many of the rules. First of all, when the solid form
of the substance melts, its density increases, so a lump of it floats in a jar of it ... very rare behavior.

And not only that! From the temperature where it melts until another 4 Celsius degrees warmer,
the stuff keeps getting more dense, before it finally starts expanding as the temperature increases
further. Very rare, and very weird. It's either the only known substance, or one of only a few known,
that behave like that.

This unusual substance with its rare behavior is "Hydrogen hydroxide". Better known as 'water'.

Answer 4

Water is at its maximum density when it is fully saturated at 4 degrees C. less salinity and higher or lower temperatures decrease ocean density.

Answer 5

because a higher pressure in a smaller area means there is more of a substance in the area ie greater density

Answer 6

Because Helium isn't involved
