Mass Density. (Chapter 12). Pressure. Buoyant Force. (Chap. 13). Lecture Density ratio of its density to that of water. Sep there are enough nails so that the pressure, Pressure in a liquid depends on depth. Specific gravity is defined as the ratio of the density of the material to the density of water These are only two of many examples of pressure in fluids. The tip of a nail exerts tremendous pressure when hit by a hammer because it exerts a. Understand the relationships between temperature, volume and density in a Understand the effect of changing the pressure or the temperature of a gas Predict the spatial distribution of particles in samples of solid, liquid and gas as The volume of the nail increased by cm3 when the temperature was increased.
Space and Volume Volume measures the spatial size of an object.
Static Fluid Pressure
Although the formula used to calculate volume depends on its shape and can be complicated, you can think of it generally as width times height times length. Measuring an object's volume can sometimes be easier than calculating it. Putting it into a large container of water and measuring the rise in water level can quickly find the volume, no matter what shape it is.
Density is sometimes used to describe other quantities divided by volume, such as energy density. The densities of thousands of substances, including metals, plastics and more, are well-known. At room temperature and pressure, the density of a given substance is almost always constant--an iron nail and an iron boat anchor both have the same density though they are very different things.

A king had asked Archimedes to determine if his new crown was made of pure gold, but without damaging it in any way. Notice that the plots all have the same origin of 0,0: The only difference between these plots is their slopes.
The general meaning of density is the amount of anything per unit volume. What we conventionally call the "density" is more precisely known as the "mass density". These very high densities represent the ultimate limits of how much mass can be packed into a given volume. The following chart will give you some feeling for the values of density found in nature generally topin common solids middleand in gases and liquids bottom.
Density and its Applications - Chemistry LibreTexts
To the extent that a gas exhibits ideal behavior low pressure, high temperaturethe density of a gas is directly proportional to the masses of its component atoms, and thus to its molecular weight. Measurement of the density of a gas is a simple experimental way of estimating its molecular weight.
Mercurybeing a liquid metal, is something of an outlier. It may not seem like there is any air under the chessboard when placed on the table but the roughness and cracks of the chess board are enough to allow air underneath.
How does pressure affect density of fluid?
If you could get rid of all the air underneath the chessboard and prevent air from being allowed to sneak back in, that board would be stuck to the table like a suction cup. In fact, that's how suction cups work. They push the air out to create less pressure inside than out. The smooth plastic of the suction cup prevents air from sneaking back in. The higher pressure outside air pushes the suction cup into the surface. If you wanted a formula for the total pressure also called absolute pressure at the top of the can of beans you would have to add the pressure from the Earth's atmosphere P.
