hey guys, i need help again. wut iz density?
http://www.kidsgeo.com/geography-for-kids/0084-pressure-and-density.php
um i tried that site and then i get confused on where to go
This is the first paragraph in the above link.
"Because all objects are made out of molecules it is possible to determine how tightly packed those molecules are. This is known as density. The more tightly packed the molecules of an object, liquid or gas are, the more dense we say they are."
Also -- Aaron -- please do not post "answers" to questions which you do not understand.
ok ok srry i got the answer off ask
Hey there! I'm here to help you understand what density is.
Density is a physical property of matter that describes how much mass a material has in a given volume. It is commonly denoted by the symbol "ρ" (pronounced as "rho").
To calculate the density of an object or substance, you need to know two things: the mass and the volume. The formula for density is:
Density = Mass / Volume
The units of density can vary depending on the units used for mass and volume. For example, if you measure mass in grams (g) and volume in cubic centimeters (cm³), then the units of density would be grams per cubic centimeter (g/cm³). Other common units of density include kilograms per cubic meter (kg/m³) and pounds per cubic inch (lb/in³).
To find the mass of an object, you can use a balance or a scale to measure its weight. To determine the volume of an object, different methods can be used depending on its shape. For regular geometrical shapes like cubes or spheres, you can use mathematical formulas. For irregular shapes, you can use techniques such as water displacement.
It's worth noting that density is often used to identify and compare different materials. For example, materials with a higher density are generally heavier compared to materials with a lower density.
I hope this explanation helps! Let me know if you have any further questions.
