the temperature and the salinity
Salt water density really depends on a few different things. The concentration of salt and temperature are the 2 largest factors in determining the density of salt water.
One real-life example of density is the layering of liquids in a salad dressing; oil, which has a lower density than vinegar, floats on top. Another example is the sinking of a wooden log in water; while the wood has a lower density than the water, if it is saturated with water, it can sink, demonstrating how changes in density affect buoyancy.
muscle density and bone density
i think only 2 things effect on sound under water, temperature and pressure.
The density of any substance remains the sameirrespective of its volume.
Not necessarily. Density is mass divided by volume. Many different things could have the same density.
Colour, density, mass
Density depends on 2 things, mass and volume. If you don't know the volume you cannot calculate the density.
In order to find the volume of a liquid you first need to know its mass and density. You can then use the formula: volume = mass / density. For instance, if you have 2 kg of water, you can find out the volume that the water occupies. Water have a density of around 1kg/liter. We then use the mass/density formula:Volume = mass / density = 2 kg/(1 kg/liter) = 2 liter.We have now calculated that 2 kg of water occupies 2 liter of space, or 2 cubic decimeter (2 dm^3).
what 2 things did the colonists get from the water front
No. Objects will only float in water with a density that is less than 1. This is not always true if another substance is in the water, such as salt.
1. Because the density of sodium chloride is higher than the density of water. 2. Sodium chloride is soluble in water.
