What describes how much something weighs compared to its size?
Density describes how much something weighs compared to its size. It is calculated by dividing the mass of an object by its volume, and it helps determine whether an object will sink or float in a fluid. Objects with higher density will sink in a fluid, while those with lower density will float.
Does the density of an object tell how massive something is?
No, density and mass are related but not the same. The density of an object is the amount of mass it has per unit volume, while mass is the quantity of matter in an object. So, while density can give information about how tightly or loosely packed the matter in an object is, it does not directly tell you how massive something is.
If something is bigger than something does it mean it weighs more?
Not necessarily. Size and weight are two separate characteristics. Something can be larger in size but weigh less due to differences in density.
Name something that's worth more if it weighs more?
Gold is worth more as it weighs more due to its high density and value.
What does the word dense mean?
The "density" of something is a measure of how much it weighs (technically, it's mass) per amount of space it takes up (it's volume). The formula for density is Density = mass/volume. So something that is very heavy but doesn't take up much space is considered to have a high density (like lead), but something that is light and takes up a lot of space has a low density (like feathers). So the word "dense" usually refers to things that have a high density. It is also commonly used colloquially to refer to somebody who is maybe a bit slow to understand things (I think it is reference to their skull being dense, thus not allowing much in or out of their brains!). Density = Mass / Volume Plutonium is very dense. Styrofoam isn't. Water has a density of 0. Density is the consitration of matter in an object
