The mass of a volume of a material depends on its density. A cup of water is likely to have less mass than a cup of sand, because the density of rock is generally much greater than water, and sand is fine particles of rock.
Sand can be packed into a cup at different densities, but even if only lightly poured into the cup, the air between the sand particles will not be sufficient to make the density lighter than that of water, as most rock is at least twice as dense as water.
Some rocks are apparently less dense than water: they even float! But, this is because they have trapped air bubbles in them which lighten them, and once ground into sand, they will be much denser as the air is no longer trapped within the rock.
Some examples of densities are:
- water 1 g/cm3
- granite 2.7 g/cm3
- sandstone 2.3 g/cm3

What is heavier bottle of water or cup of water?
A cup of sand, sand sinks in water, thus its heavier.
What is heavier 1 gallon of water or 1 pound of sand?
1 gallon of water is heavier than 1 pound of sand. Water has a density of 8.34 pounds per gallon, so 1 gallon of water weighs more than 1 pound of sand.
What would happen if the stirred each of these cups faster water and sand?
If you stirred the cup of water faster, the water molecules would move more rapidly, creating more turbulence and possibly generating waves or splashing outside the cup. If you stirred the cup of sand faster, the sand particles would move more vigorously, possibly causing some of the sand to spill out of the cup due to the increased momentum and force.
Does sand sink in water because water it is more dense then sand?
Essentially, sand is more dense and has more mass, thus it sinks. durr. hi
How do you make water weights heavier?
You can make water weights heavier by adding more water to the container or by using a denser liquid, such as sand or gravel, in combination with water. Increasing the volume or density of the liquid will increase the weight of the water weights.
What is heavier bottle of water or cup of water?
A cup of sand, sand sinks in water, thus its heavier.
Is sand heavier than water?
yes sand is heavier than water:)
What heavier sand or water?
water
How many pounds are there in cups?
a cup is considered a liquid measurement, not weight. eg: what is heavier, a cup of feathers or a cup of sand?
Is a cup of water less or greater than a cup of sand?
1 cup of water is the same volume as 1 cup of sand.
Which weighs more 5 gal of sand or 5 gal water?
Sand is heavier than water.
Why does sand sink in water?
Sand and water both have weight and both have volume. A cup (volume) of sand weighs more than an equal volume of water. So the sand pushes the water out of the way and sinks. A cup of wood chips weighs less than an equal volume of water. So the water pushes the wood chips out of the way and they float. Try it and see.
Why does sand sink to the bottom of water?
Sand has a higher density than water, so it sinks to the bottom when placed in water due to gravity pulling it down. The sand particles are heavier and more compact than water molecules, causing them to settle at the bottom.
What happen when sand mixed with water?
Nothing - sand and water do not react because sand is relatively inert. The sand will sink to the bottom of the container because it is significantly heavier than the water.
What is heavier a grain of sand or the air?
A grain of sand is heavier than the same volume of air because sand has mass and air is mostly composed of gases, which have lower density and weight.
How much does a cup of lard weigh?
The cup of water is slightly heavier.
Does a cup of water have more grams than a cup of oil?
Yes, because water is heavier than oil.
