When a solid block of materials is cut in half what happens to the density?
The density does not change, as density is the amount of material in a given amount of space. But each piece has the same amount of space and material relative to each other.
How does the density of a 100-kg iron block compare with the density of an iron filing?
The density of iron is 7,874 kg/m3 or 7.874 g/cm3. The density of iron filing is somewhat lower depending upon how fine the filings are, but I guess more than 4000 kg/m3 or 4.0 g/cm3. The SI standard of density is measured in kg/m3. The density of a material is defined as its mass per unit volume. The density of iron does not change with the size of the sample. A bucket full of iron filings will have a lower density than the block because there will be air between the individual filings. The density of a deep pile of filings will be greater than a thin pile because the weight of the filings above compacts the filings below by pushing out some of the air. However, the density of each individual piece will still be the same as for the whole block.
If a block weighs eight kilograms plus half a block what is the weight of a block and a half?
24 kilograms. I say this because 8kg plus half a block is a whole block. The half a block has to be also 8 kg making a whole block weigh 16 kg. Now 1 block (16kg) plus half a block (8kg) added together is 24kg
How would you determine the density of an irregular shaped rock?
Not always easy. Since density is defined as the mass of a unit volume of material,you would measure the volume of the rock by putting it into a container half filled with water and then measure the volume change.
By how much does the density of air increase when it is compressed to half its volume?
Density is inversely proportional to volume. If volume changes to half, density doubles. The substance doesn't matter.

What will happen to the mass volume and density if you chop the wooden block in half?
The volume will be reduced to a half of its original value. If the mass is (approximately) evenly distributed throughout the wooden block then the mass will also reduce to a half of its original value and the density will not change.
A wooden block has a mass of 1000 kg an a volume of 2 cubic meters What is the blocks density?
1000 kg/ 2 m3 = 500 kg per cubic meter density or 0.5 g/cm3 or approximately half the density of water
What would be the destiny if you had a sample of the same material that was half the size?
Same density. Density is a property of the material and is independent of how much there is of it. That's why properties are important. Now the destiny of that material...I imagine it will eventually end up in a land-fill.
Example of a opaque material?
A half inch thick steel plate, A half inch thick plywood, Brick, Concrete Block
What is the density of a block of wood with a volume of 20 cubic centimeters and a mas of 60 grams?
Density = mass/volume = 60/20 = 3grams/ccNote:The Physics and the math in this answer are bullet-proof, but there is no woodon Earth with even half that density. I suspect your block has a concrete center.
When A block of oak wood with a volume of 405 cubic centimeters and a density of 0.67cm is sawed in half the density of the two smaller blocks is now?
it is the same because the molecular structure did not change when you cut the wood in half.
Would the density of a block change if you cut it in half explain your answer mathematical reasoning and the word ratio?
No it will not change. Density is mass divided by volume. Since the ratio of the mass is 1/2 and the volume ratio is 1/2, there is no change. The same holds true no matter how you cut the block, as both mass and volume change proportionally the same.

If aluminum bar is cut in half What is the density of each half compared to the original density of the bar?
It is going to need to be divide by the original density and then after you find that out you get your answer.
if a block weighs eight pounds plus half a block whats the weight of block and a half?
4 pounds?
