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.

When a helium balloon rises in the air it expands. If the volume of the balloon doubles what happens to the density of the helium inside it?
The density will be 50 % from the initial value.
What is the density of a metal if you cut it in half and the original density was 8.4?
The density is the ratio of mass to volume. It doesn't matter what size the piece of metal, if it is the same metal it has the same density, 8.4.
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.
When a helium balloon rises in the air it expands If the volume of the balloon doubles what happens to the density of the helium inside it?
The density is reduced to 50% (half) of its original value.
Does cutting an object in half change the density?
The density of something is the mass divided by the volume, so if you cut the item in half, it will not change the density at all. Instead, the two halves of the item will have the same density.
If One kg of air is compressed from 1 m3 to 0.5 what happens to density?
Density is a measure of mass per unit of volume. Assuming no air leaks out while we compress it, the mass doesn't change. Since the volume is now half as much as before and the mass is the same, the density has doubled.
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.
When a balloon is heated its volume is doubled what happens to its density?
The density decreases by half. You find the answer by knowing that density is equal to mass divided by the volume. If the mass stays constants and the volume is doubled, then the density is halved.
What if pressure is applied to a cube until its volume is half of its original volume what will its new density be?
If the volume is halved, without change in mass, the density will be doubled.
When a Balloon is heated it's volume doubles . What happens to its density?
The density decreases by half. You find the answer by knowing that density is equal to mass divided by the volume. If the mass stays constants and the volume is doubled, then the density is halved.
When a balloon is heated it's volume doubles what happens to its density?
The density decreases by half. You find the answer by knowing that density is equal to mass divided by the volume. If the mass stays constants and the volume is doubled, then the density is halved.
How does the density of the whole crayon compare to the density of half of the crayon?
Its the same, even though the mass is smaller, so is the volume, there for the mass to volume ratio stays the same when you cut it in half.
What is the density of a nickel if it were sawed in half?
It is unchanged. The density is the mass divided by the volume, and as both of these numbers are halved the density does not change.
How is density a size-independent property?
Purely from a definitional sense, density is size independent because it depends on the substance in question, not how much of it you have. From a mathematical sense, density is mass/volume. If the mass is equally distributed throughout the volume, then half of the volume, for example would have half the mass, preserving the same value of density.
What is the density when volume doubles?
When volume doubles density is cut in half. D=M/V D=12/6=2 D=12/12=1
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.
Does the volume of something change if cut in half?
Nothing, the density stays the same.
