It is going to need to be divide by the original density and then after you find that out you get your answer.
hey my name is****** b***** this is half of the question and it is easy. so do it urself from this buckledown book.
This is incorrect. A bar of lead is denser than a bar of iron. Iron bars have a density of 7.87 g/cm3, whereas lead bars have a density of 11.36 g/cm3.
a physical change is not a chemical change as it changes the physical appearance of the substance like state, color, size and shape
Exactly the same.
The density does not change.
you can because say it was 100 then you would have it it would be 50 then you would half 50 witch is 25.
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 candy bar was cut in half the mass would decrease.
The density of the chocolate bar will remain the same, even if the bar is cut in half, or any other fraction. Only if the chocolate was to be melted, will the density change from a solid to a liquid.
remains the same
Melting a candy bar is a physical change because it is just changing form, not changing the chemical makeup. (If it isn't making a new material, it is not a chemical change)

Density refers to a given mass in a certain volume, so the volume and mass would both become smaller by he same amount.
