Equal volumes may have different weights for many reasons, for instance:
1. The densities of the substances may be inherently different. This happens with non food items too, for instance a cubic metre of aluminium weighs less than a cubic metre of iron.
2. Powders can pack differently, so one may have more air spaces.
3. One substance may be damp.
Of course not...different densities, different volumes per same weight.
Two objects can have different volumes but the same density if they are made of different materials. Density is a measure of how much mass is packed into a certain volume, so objects with different volumes can still have the same density if their masses are adjusted accordingly.
WATER
Because many of them are powders. The same weight of a powder can have many different volumes, depending on how much air has been fluffed into it. For example: When you sift flour, you get more volume out of the sifter than you put into it, although the sifter obviously doesn't change the weight of the flour.
Capacity is referring to volume, not weight. Weight is the force of gravity acting on an object. 1 pound of lead and one pound of wood have the same weight (1 lb) but they have very different volumes (capacities).
Yes, items with the same mass can have different volumes due to differences in their densities. Density is a measure of how much mass is contained in a given volume, so two items with the same mass but different densities will have different volumes. For example, a piece of lead and a piece of aluminum can have the same mass but different volumes because lead is denser than aluminum.
different equal
Yes, you can.
You need to specify what the liquid is that you are measuring. The liter is a measure of volume, and the stone is a measure of weight. Liquids with different measures of specific gravity (similar to measures of mass for solids) will fill different volumes at the same weight.
Different metals have different volumes for the same mass.
it depends on the density of what you are comparing. Pints is a measure of volume while grams is a measure of weight, so it is impossible to answer since the same volumes of different things weigh different.
Yes, they can. They can also have the same surface area, but different volume.
