Density is the amount of a substance contained within a specific area. Density is the mass divided by its volume and is expressed in units like grams per cubic centimeter or pounds per cubic foot. Density measured in units of g/ml is also known as specific gravity. Specific gravity is defined as the density of a given object divided by the density of pure water at 4?C. Because the density of pure water at 4?C is exactly one g/ml, the specific gravity of an object is simply its density divided by 1 g/ml.
Density can be measured in lots of ways. Solids are weighed to determine its mass then put in water to measure the volume. From that point its mass and volume are divided to give you the density of the solid. .
To find the mass of a liquid you must first measure the container that you are going to put the liquid in. Put the liquid in the container and find the measurement. Subtract the weight of the container and you will have the mass of the liquid. The volume of a liquid can be determined by something as simple as a measuring cup used for cooking. From that point you would use the same method for liquids as you would for solids.
Hydrometers are used to measure specific density of liquids. Some hydrometers are enclosed in a glass tube held with a lead weight or mercury. When immersed the graduated stem rises vertically to give a measurement. .

An example in determining the density of a solid is to get a graduated cylinder and a rubber stopper and following this procedure:.
1. Get a rubber stopper and a graduated cylinder.
2. Wash the stopper to remove dirt, dust, etc.
3. Let it dry and then find its mass by using a triple beam balance.
4. Put enough water in the cylinder that is higher than the stopper.
5. Turn the cylinder at an angle when you drop stopper so it doesn't splash.
6. Record the volume of the stopper.
7. Now by using the density formula D=m/v you will get the density.

The purpose of this lab is to determine the density of water, the density of an unknown liquid and the density of an unknown solid. ... DENSITY OF AN UNKNOWN SOLID 1. ... DENSITY OF A SOLID 1. ... The true density of the unknown liquid was .785 g/ mL. ... DESCRIBE BRIEFLY A GENERAL METHOD THAT COULD BE USED TO DETERMINE HE DENSITY OF A SOLID AND A LIQUID? ...
These beakers are the sources for the pure liquids. ... Finally, calculate the density. ... Suppose you were to determine the density of a solid-how will the procedures and results differ from that of a liquid. ... To get the densities from a solid and liquid, the procedure is the same. You can use water to measure the volume of both a solid and liquid. ...
A solid object's density determines whether or not the buoyant force of a liquid can lift it. The density of an object depends upon its mass and its volume (Density=mass/volume). Given two solid objects that have different volumes, but have the same mass, the smaller object is the denser of the two. ... Fluids also have density. When an object is placed in the fluid, it pushes aside some of the liquid and, if its density is greater than that of the fluid it displaces, it will sink and, if not, it will float. ...
In fact, water should be a gas at RTP, and has a much stronger surface tension and higher viscosity than most other liquids, and the density of its solid form is less than that of its liquid form. ... Ten times stronger than Van der Waals' forces, they occur when the electron density changes around the atoms : the electronegative atoms gain electron density whereas the hydrogen looses it, in such a way that it is almost donating an electron. ... It also accounts for its viscosity, as the bonds are stronger, the molecules are harder to move and separate, and this makes the liquid "harder t...
In 1829 Johan Dobereimer first classified elements into a system of so-called triads. Previously, there were so few discovered atoms that this was impossible to group atoms in any way. Johan's system was a pioneer in a series of scientific attempts to accurately place like elements, discovered and ...
It is distinguished from the underlying mantle rocks by its composition, lower density, and the lower velocity at which it conducts seismic energy. ... The last layer is the core, which is separated into the liquid outer core and the solid inner core. ... The lithosphere contains all of the cold, hard solid land of the planet's crust, the semi-solid land underneath the crust, and the liquid land near the center of the planet. ... The solid, semi-solid, and liquid land of the lithosphere form layers that are physically and chemically different. ... The hydrosphere contains all the solid, l...
It was solid and slightly elastic, it was also slightly grainy likely due to the addition of too much boric acid or an excess of diethyl ether that was in the final solution. ... Silicon the element can be used to make concrete and brick, while hyper-pure silicon is used in solid state hard drives and many other solid-state electronics.2 Silicones are extremely useful because they are water repellent, heat stable, and very resistant to chemical attack. ... The remaining diethyl ether was then boiled off and the yield of the liquid polydimethylsiloxane ([CH3SiO]n) was recorded. A spatula of bo...
It was also an important chemical for medieval alchemists, suspected of being an element of which all matter was made from, and when it was solid it was thought to become gold. ... Mercury is known as "quick silver- because it is liquid and is silver-white in appearance. ... It is the only common metal that is liquid at room temperature. ... Its density is 13.534, which is 13.6 times greater than the density of water. ... It has many distinct physical and chemical properties, including being the only metal that is liquid at room temperature. ...
