What is a trait of a substance by itself?
Substances have many different traits, which include such things as phase (solid, liquid, or gas), density, hardness, color, reactivity, flexibility, scarcity or abundance, toxicity, etc.
Microscopes produce images by focusing light rays and beams of cells?
Microscopes produce images by focusing light rays or beams of electrons. An instrument used to separate cell parts according to density is the centrifuge.
Is earthquake-related tsunami a density dependent factor or density independent factor?
density independent factor
What is special about water and density?
Density rho = mass / Volume. Water has a density of 1,000 kg/m3 = 1,000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL at the temperatur of 3.98 degrees Celsius. Temperature in degrees Celsius and the density of water: 1 999,902 999,943 999,964 999,975 999,966 999,947 999,90 You see the highest number at 4 degrees Celsius.
What are the similarities between density-dependent factors and density- independent factors?
Density dependent factors are factors that depend of the population (density). Such as food, water, and space Density Independent factors are factors that the population (density) depends on. Such as weather, natural disasters and random occurances.
What property does separation by density rely on to separate out parts of a solution?
Substances with different densities will separate into layers.
To separate the parts of a cell by differences in density a biologist would use what?
an ultracentrifuge
When two unlike air masses what usually keeps them separate?
Density differences is usually what would keep air masses separate.
What phytsical prperty of substances makes it possible to separate a mixture by spinningit at high speed?
relative density
When two unlike air masses meet what usually keeps them separate?
Density differences is usually what would keep air masses separate.
How can you separate substances of different densities?
Density Column to Separate Mixtures of SolidsYou could use a density column to separate mixtures of different solids by adding substances that have different densities. Then you would add in the solids, which would land or stop at a substance.
How do you label the substances in order by density in a test tube?
If the substances in question remain in the form of separate layers, rather than dissolving into each other, then the densest one will be on the bottom, and with progressive height in the test tube, you will get progressively less density. Denser substances will fall through less dense substances.
What do convection currents form?
because of differences in pressure and density in a fluid
What forms because of differences in temperature and density of a fluid?
convection currents
Why is density characteristic property?
Density is a Characteristic Property because it is A quality of a substance that never changes and can be used to identify the substances.
Density of an object is less than density of water?
It is for some substances and not for other substances.
Why separation flow occur in annular pipe?
Because of differences in viscosity and density.
