What is the difference between density and matter?
The difference is that Density is one way of measuring matter, its a math expression. While Matter is a physical substance.
Is the density of a kilogram of iron less than th density of one gram of iron?
The density should be identical regardless of the quantity, because "density" is what's called an intrinsic property; it doesn't matter how much of the substance there is.
What is the amount of matter in a given unit volume?
That depends on the substance being studied. "Given unit volume" means 1 liter, for instance, or one cubic centimeter - the specific volume being discussed. Once cubic cm of water would have less matter (is lighter) than one cubic cm of lead (is heavier.) Think about it this way - the more tightly packed a substance is, the more matter there is in one cubic cm of that substance. This is called the substance's DENSITY. If this is a hw problem you're trying to solve, you multiply the volume of substance by that substance's density (which you should find in a table or whatever.) Mind your units!
Why does one substance float over another?
A substance floats over another substance if it is less dense. Density is a measure of how much mass is in a given volume, so if one substance is less dense than another, it will float on top. This is due to the buoyant force exerted on the less dense substance by the denser substance.
Does one ml have the same density of 15 liters?
Any sample of the same substance has the same density,no matter how large or small the sample is.
One of the factor affecting density?
One of the factors affecting density is temperature. Because the particles spread more apart when heated, the hotter the substance is, the less dense the substance gets. another one has six letters that describes all of it is energy!!
What determines whether one will sink or float in another?
The density of an object is what determines whether it will sink or float in another substance. If the object's density is greater than the substance it's placed in, it will sink. If the object's density is less than the substance it's placed in, it will float.
What substance has a density less than 1 gmL?
For example ice and lithium.
A property of matter that can be observed and measured with out changing its density?
One property of matter that can be observed and measured without changing its density is its color. The color of a substance can be determined visually or quantitatively using instruments like a spectrophotometer, without altering its density.
Which property determines whether one substance will sink or float?
The density of the substance compared to the density of the fluid it is placed in determines whether it will sink or float. If the substance is denser than the fluid, it will sink. If the substance is less dense than the fluid, it will float.
What is relative densities?
Relative density is the ratio of the density of a substance to the density of a given reference material.If a substance's relative density is less than one then it is less dense than the reference; if greater than 1 then it is denser than the reference. If the relative density is exactly 1 then the densities are equal
What physical property of matter tells how concentrated matter is?
Density is a physical property that is often correlated with chemical composition. For example, most metals are denser than any non metal elements, and most hydrocarbons are less dense than water.
