# Can Two Things Have The Same Density?

## Do objects of the same material have the same density?

Unlike the mass and volume that may be different for each specimen, all objects made of the same material will have the same density.

Because of this the density is often used to identify unknown substances or to determine the percent composition..

## What is density compared to?

Key Concepts. Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance.

## Does density change with size?

Density is an intensive property. This means that regardless of the object’s shape, size, or quantity, the density of that substance will always be the same. Even if you cut the object into a million pieces, they would still each have the same density.

## Why is water’s density 1?

It’s no coincidence that water has a density of 1. Density is mass divided by volume (ρ=m/v), and water was used as the basis for establishing the metric unit of mass, which means a cubic centimeter (1cm3) of water weighs one gram (1g). So, 1g/1cm3 = 1 g/cm3, giving water its easy-to-remember density.

## What happens if two objects have the same density?

If the object is of equal density it will sink into the water so that no part of the object is above the surface. It may or may not “float” just but entirely below the surface. As eigenperson said, if pushed down it might stay at the new depth but that’s tricky. If the object is of greater density it will sink.

## What is the most dense liquid?

MercuryMercury is the densest liquid at standard conditions for temperature and pressure (STP). Also called quicksilver, mercury has been known for more than 3,500 years. It is an important metal in industry, but it is also toxic.

## What 3 liquids will not mix?

Three liquids that don’t mix include honey, corn syrup and liquid dishwashing soap. These liquids, when poured in one container, form layers. Other liquids that do not mix include water, vegetable oil and rubbing alcohol. Liquids that don’t mix are called immiscible liquids.

## What is the least dense liquid?

Lowest density liquid in nature Self-binding of helium-3 in two dimensions. Quantum matter consisting of light particles can stay liquid or gaseous without solidifying even at absolute zero. Such matter is termed a quantum liquid or quantum gas.

## How is density calculated?

Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume.

## How do you compare the density of two objects?

If you compare the weight of two objects of the same size and shape (the same volume), the one that weighs more is more dense. So, if you weigh a piece of clay and a piece of wood that are the same size and shape, the clay weighs more than the wood, so the clay is more dense than the wood.

## What is density in simple words?

Density is a measure of mass per unit of volume. … The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).

## Which liquid is heavier than water?

Mustard oil & mercury are some of the liquids that are heavier than water.

## What does it mean when two objects have the same mass?

Density is known as the amount of substance present in a liter. … Whereas mass present in a substance means the amount of matter present in it. Hence, we can conclude that if two objects have the same mass, then it is true that they contain the same amount of matter.

## Can two objects have the same mass but different densities?

The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). The mass of atoms, their size, and how they are arranged determine the density of a substance. … Objects with the same volume but different mass have different densities.

## Can two different liquids have the same density?

Two liquids that have the same volume don’t necessarily have the same density. Density = mass/volume, so they would only have the same density if they also have the same mass. Density is an intensive property, which means that it doesn’t depend on the amount of the substance present.

## What has a higher density than water?

clayEven though it’s lighter, the piece of clay has a higher density than water and therefore sinks. Even though it’s heavier, wax has a lower density than water, so the big candle floats.
