The "density" of water is more specifically known as its Specific Gravity. Specific Gravity uses water as its base number (1.0). This means that one Litre of water weighs exactly 1Kilogram. Bear in mind that the water must be pure and distilled, or its Specific Gravity will change diminutively. Why is Water the base number for all Specific Gravities? because it is the most common liquid. If you want to know the "density" of a liquid, all you have to do is measure a litre of it into a jug and weigh it. Say the weight of a litre of shampoo is 1.8Kilos; that means 1.8 is the Specific Gravity of shampoo! Easy!
The formula is D = m / v
first you must find mass of water. To find it just measure a beaker, then water in that beaker and subtract beakers mass.
Then you have to find volume. You pour water in burette, and look how much is it.
Finally dived mass by volume.
Firstly obtain a known volume of fresh water, say 100cm3. Then weigh the water and plug your values into the equation:-
density = mass/volume
ensure that mass is measured in g and volume in cm3 to obtain a density value in gcm-3
Water has a density of 1gcm-3
you multiply the mass and volume together to get the density answer :) :P
volume per unit mass
no, mass per unit volume!
mass divided by volume
throgh a ball in the air and see if it comes down
Density of liquid can easily be measured by dividing its mass by its volume.
Density=mass/volume
this formula is also valid for liquid.
The density of water is 1 g/ml2
1 gm/cm^3
Hydrometer measure the density of liquids.
Salt waters of the Atlantic
Estuary
Planaria exist only in fresh waters.
1 gm/cm^3
Surface mixed zone
If an objects density is greater than the waters density it will sink but if it's density is less than the waters density it will float
Sink.
You think probable to the movement of salt waters into fresh waters.
In ground waters
Hydrometer measure the density of liquids.
The density of seawater is approximately 1030 kg/m3Note that:1. Density is a measure of the mass per unit volumeIt does not depend on the sample's size.2. The density of seawater is greater than that of fresh water which has a density of approximately 1000 kg/m33. The density of water varies with temperature and impurities.
because they're too fresh for fresh water
Same as sanitary waters.
Salt waters of the Atlantic
Density = mass/volume.
