Density
Density is mass per unit of volume. Density also shows how tightly packed in molecules are in a material and also help determine buoyancy.

What does density have to do with convection?
Things with a lower density will float on things with a higher density.
If you take a fluid (air or water) and heat it, the portion that is heated usually expands. The same mass takes up more volume and as a consequence the heated portion becomes less dense than the portion that is not heated.
Get it? Hope you do!
The density of H2O is 0.9982g/mL at 20°C. Usually a value of 1 is used at room temperature.
What is the density of petrol?
737.22 kg/m^3
The density depends on a whole range of factors including purity and Temperature. Use the above as a guide though but in situations where the value of density is critical, take a sample to the lab for them to determine the correct value.
The density of a substance is its mass divided by its volume. It is a physical property that measures the amount of mass in a given volume. It is typically expressed in units such as grams per cubic centimeter (g/cm3) or kilograms per liter (kg/L).
The density of a penny is approximately 7.9 grams per cubic centimeter.
What is the density of silver?
You can calculate density with the formula density = mass/volume.
The density of pure silver is 10.49 g/mL or 10.49 g/cm3.
Of course silver is frequently alloyed so the density of the alloy may be a bit different - but probably still somewhat close to the density of pure silver since it should be mostly silver.
Neon's density at standard conditions is 0.9002 grams per cubic centimeter.
What is the density of Sprite?
I am not sure about Sprite, but I do know that original soda is 0.746 Kilograms per liter.
What is the density of bamboo?
The density of bamboo can vary depending on the species and age of the bamboo. On average, the density of bamboo ranges from 0.4 to 0.8 grams per cubic centimeter.
To obtain the answer, use these algebraic equations : 8 cm3 Cu + 7 cm3 Sn =121 g 9 cm3 Cu + 11 cm3 Sn =158 g Analyzing the two equations, we find that 72 Cu + 63 Sn = 1089 g 72 Cu + 88 Sn = 1264 g and 25 Sn = 175 g Sn = 7 Tin has a density of 7 g/cm3 and Copper has a density of 9 g/cm3.
What is the density of a penny?
Density is 7.18 g/ml for post 1982 which is quite close to that of Zinc density of 7.14 g/ml. This makes some sense since the coin is 97.5 % Zinc and 2.5 % copper with a density of 8.92g/ml.
The mass is:
3.11 grams [pre 1982]
2.50 grams [post 1982]
The findings of a physics class:
I calculated it in my physics lab with a group of students -
To attempt to approximate for the different amount of nickel found in a penny past 1998, we took the avg of ten coins for thickness and mass. The density was found to be equal to 6.60 grams/centimeters cubic (approximately).
The density of PVC (polyvinyl chloride) typically ranges from 1.3 to 1.45 grams per cubic centimeter.
What is the density of medium density fiber board?
Medium Density fiber board is 48 lb. board. High Density Fiberboard is 55 lb. board. Low Density Fiberboard is 38 lb. board. Ultra Light Fiberboard is 33 lb. board.
The density of polypropylene is typically around 0.895 grams per cubic centimeter (g/cm^3). It is a lightweight and versatile thermoplastic polymer that is widely used in various applications due to its excellent balance of properties such as strength, stiffness, and chemical resistance.
volume per mass or volume/mass. Ummm can anyone check up the word rho i think that is the unit!!!
The density of oak wood can vary depending on the species, but on average it is around 0.75 grams per cubic centimeter.
Density is used to describe how much mass is packed into a certain volume. It is used to identify and compare materials, calculate buoyancy, determine purity of substances, and predict behavior of objects when interacting with other materials.
Gaseous hydrogen has a density of 0.08988 g/cm. Liquid and solid hydrogen have a density of about 0.07 g/cc
At standard temperature and pressure (stp), hydrogen as a gas has density 0.08988 grams per litre. Hydrogen atoms have atomic mass of 1, and diatomic hydrogen molecules have molecular mass of 2. From this we can tell that hydrogen is the lightest (least dense) element in the periodic table.
Each material has its own density!
Examples: Solid - water - noble gas
Copper has a density of 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3.
Water has a density of 1000 kg/m3 = 1000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL.
Helium has a density of 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L =
0.0001785 g/cm3 = 0.0001785 g/mL.
The density of methanol at room temperature (20°C) is about 0.7918 grams per cubic centimeter.
What is the definition of density?
Density is a property of matter representing the mass per unit volume. :)
How is viscosity and density related?
Viscosity is the thickness or thiness of a fluid, Density is the space between particles.
When a fluid is heated, it becomes less viscous(thinner) and the particles move far apart so it is less dense. Temprature affects density and viscosity.
Something that is dense doesn't have to be viscous and vice versa.
EX: Salt water is dense but not viscous.
Honey is very viscous but not very dense
How is density related to floating?
You must compare the densities of the object and whatever substance you are putting it in. If the density of an object is greater than the substance it is in, then the object will not float on the surface

The density of a material is defined as its mass per unit volume.
The density of liquid water is normally given as 1000 kg/m3 or 1 g/cm3 as a very accurate estimate, but often ranges slightly below this value, depending on temperature.
Unlike other agents that tend to freezing point, water tends to expand as at freezes; it therefore becomes less dense. Thus, the density of solid water is normally given as just over 91% of this; a common given value is 9.17 g/cm, or 9170 kg/m3.
