Learn about density with an easy example of a styrofoam cup. Understand the concept step by step using a fun analogy. Get a clear explanation of how to calculate density in a child-friendly way.
Hey there! Let's talk about density using a simple example with a styrofoam cup. Density is like how tightly packed the stuff inside an object is. Imagine your cup is like a box of toys. If you stuff a lot of toys into a small box, it will be heavy. That's density!
Now, let's find how dense the styrofoam cup is. First, measure how much space (or volume) the cup takes up – like counting the number of toys you can fit inside. The cup's volume is 500 cubic centimeters, think of it like this cup can hold 500 toy blocks inside.
Next, we need to know how heavy the cup is – the mass. The cup's mass is 20 grams, which is like the weight of the cup itself.
To find the density, we can use a cool formula: Density = Mass ÷ Volume. Think of it as how many toys (Mass) are in each block of the box (Volume). Plugging in the numbers gives us: Density = 20g ÷ 500 cm³ = 0.04 g/cm³.
So, the density of the styrofoam cup is 0.04 grams per cubic centimeter. It means that for every cubic centimeter of space the cup takes up, there are 0.04 grams of stuff inside. That's how tightly packed the cup's material is. Cool, right?
