Changes in density in fluids are primarily caused by thermal expansion and contraction, which is a result of conduction and convection as heat is transferred. These variations in density play a crucial role in the circulation patterns of fluids, such as in the atmosphere and oceans.
The mass and density are very different.
by the the difference between their density
It has a different amount of space between molecules.
Thermohaline circulation is also called overturning circulation. It is driven by density. The time scale for thermohaine is 1000 years.
It has a different amount of space between molecules
It is due to different elasticity and density of the medium
Salinity affects thermohaline circulation by influencing the density of seawater. Higher salinity increases water density, promoting sinking of cold, dense water in polar regions. Temperature influences this circulation by controlling the density of water - colder water is denser and more likely to sink. Both factors work together to drive the global thermohaline circulation system.
If two different people use two different methods to calculate the density of a sample of the same substance, and they get two different answers, then at least one of them made a mistake. If the method of calculation makes a difference, then the whole concept of density is out the window. The only possible difference between two statements of the density of a substance should be the units in which the density is stated. But one unit can always be converted to the other, and when they're both in the same units, they had better both be the same number.
The biggest difference between bronze and brass is the density, mass, and weight. Bronze and brass are also made of different metals.
To calculate the water difference when the density changes, you would need to account for the change in volume due to the density change. Use the formula: Difference in water volume = Original water volume / Original water density - Original water volume / New water density. Multiply this difference in volume by the new water density to obtain the actual water difference.
Salt water is a lighter density than fresh. The difference depends on the salinity of the water. This differs all over the world in different parts of the oceans and in salt water lakes.
