Can 2 substances have the same density?
Finding any matching densities will give you information about the possible identity of the unknown substance.
However, it is possible for two different substances to have the same density..
Which metal is the least dense?
lithiumThe lightest or least dense metal that is a pure element is lithium, which has a density of 0.534 g/cm3. This makes lithium nearly half as dense as water, so if lithium was not so reactive, a chunk of the metal would float on water. Two other metallic elements are less dense than water.
What is the least dense element?
hydrogenUnder ordinary conditions, the least dense element is hydrogen, while the densest element is either osmium or iridium.
What is a real life example of density?
Everyday Density Examples In an oil spill in the ocean, the oil rises to the top because it is less dense than water, creating an oil slick on the surface of the ocean. A Styrofoam cup is less dense than a ceramic cup, so the Styrofoam cup will float in water and the ceramic cup will sink.
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.
Which block is more dense in the first image?
Feedback Which Block Is More Dense In The First Image? The Green Block On The Left Is More Dense.
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.
Does anything have the same density?
Density is a characteristic property of a substance. … The mass of atoms, their size, and how they are arranged determine the density of a substance. Density equals the mass of the substance divided by its volume; D = m/v. Objects with the same volume but different mass have different densities.
What is the least dense thing?
graphene aerogelThe world’s least dense solid is a graphene aerogel with a density of just 0.16 mg/cm³; produced by a research team from the Department of Polymer Science and Engineering lab at Zhejiang University, China, headed up by Professor Gao Chao (China). The material was announced in Nature magazine on 27 February 2013.
Does density change when cut in half?
What happens to the density of an object if the object is cut in half? … The density remains the same because cutting the object in half will divide the mass & volume by the same amount. Also, the density of a substance remains the same no matter what size it is. All matter has its own unique density.
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.
Which block is more dense?
Which block is denser? The block of brick because it has a greater mass then the block of styrofoam so its density is greater.
Which state of matter is usually the most dense?
Solid matterSolid matter is the most dense and compact form of matter.
How do you find the density of a block?
Density= Mass/Volume In the previous lesson you calculated the mass and volume of two blocks.
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.
Which sample most likely has the lowest density?
The first chemical element with the lowest density is Hydrogen and the highest density is Osmium.
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 did you notice about the size of the blocks and their density?
Depending on the materials of the blocks and the size determined there density. This is because the mass of a steel block will be different from the mass of a wood block. This is also because the volume of a steel block could be smaller than the mass of the wood block.
