What make's a substance more dense than another is the mass divided by the volume of the substance. The more mass it has per unit of volume the more dense the substance is. If that substance has more mass per unit of volume than another substance then it is more dense.

∙ 10y agoDensity can be calculated by the simple formula of weight divided by volume. Weight can be measured on a scale, and volume can usually be measured by means of a graduated cylinder. Once you calculate the density, you can tell which number is higher. Of course, if you are dealing with two liquids, then there is potentially an easier way; pour them into the same container and see which one sinks and which one rises. But then, they may mix together, or they may both be transparent, so this technique is not always useful. If you have one solid and one liquid, you can see if the solid floats or sinks. But then, it might also dissolve. And if you have two solids, you can't do that kind of test. So, you can always just calculate the actual density.

What is the result if an object or substance less dense than another?
then the item that is less than the other, would be lighter and both the items wouldnt have the exact same density/amount of weight.
How does a less dense substance move within a denser substances?
If it can and in a gravity field, it will float to the top of the denser substance.
What property in water makes things sink or float?
Its density.If a substance is denser than water, it will sink. If it is less dense, then it will float.(The surface tension of water also contributes slightly to this.)
Why does puffed puri float and flat sink?
Puffing it up makes it less dense. Anything less dense than water can float on water, and anything more dense than water will sink.
How do apples float?
Apples are 25% air which makes them less dense then water.
If you place a less dense substance into another substance with a greater density what happens?
It floats.
What makes balloons less dense air?
If a balloon is filled with a substance that's less dense than air ... such as helium, hydrogen, steam, or warmer air ... then the balloon is less dense than air.
How call you tell if a substance is more or less dense then water?
if it sinks its more dense if it floats its less dense
The tendency of a less dense substance to float in a more dense liquid is called what?
The tendency of a less dense substance to float in a more dense liquid is called buoyancy. Acids are substances that form hydronium ions when dissolved in water.
Do cornoil float on water?
Corn oil floats on water. It floats because oil is less dense than water. When one substance is less dense than another it rises to the top.
How can you determine whether a solid substance is more dense or less dense than water?
see if it floats, if it floats it is less dense.
Why does hot water ries?
In general, hot means the substance is less dense. Less dense things tend to rise when they are in more dense things.
Do convection currents form in the mantle when heated materials become more dense?
Actually, heated materials are less dense. When heat is applied to a substance such as liquid, it becomes less dense. It is this less dense and heated material that rises because it weighs less. The part of the mantle that is more dense would be any substance that is cooling and is sinking down.
What is the the force with which a more dense fluid pushes a less dense substance upward?
the buoyant force
Which substance is less dense than water?
dry ice
When sound travels in gas is it more dense or less dense?
The gas phase is less dense than the liquid or solid phase of a substance. Density is not a property of sound.
What makes air less dense?
polluntants
