(please put your cashapp with the answer) Density is an intensive property of a material that compares that material’s mass to volume ratio. In other words, it tells you how many particles of that substance are packed into a certain amount of space. Since density is an intensive property that is the same no matter the sample size, density is a physical property that can be used to identify a substance. In order to calculate density, you must first measure two things: an object’s mass and its volume. Density is calculated by using the following formula: Density = Mass/Volume (Mass divided by volume) Pre-lab: How do you find the volume of an irregularly shaped object like a marble? What tools would you use? Predict if the density of one marble will be different than the density of a collection of several marbles? Describe how you would mass 15 grams of salt into a glass beaker using an electronic balance without doing any math. Procedure: Log in and go to Colorado PhET Website https://phet. colorado. edu/en/simulation/legacy/density Click on the play arrow to begin the simulation. Section 1 You should notice that there is a block of wood in water and that there is a sliding scale in the upper left corner. Notice that you can “click” and “drag” green triangles to the left and right and that you can make the block of wood bigger and smaller. You can also change the block from “wood” into other substances by clicking the drop down tab. Fill in the tab below and answer the questions. Important Also click on the button that says “Show Table”. Place the block on the balance on the left side of the screen to obtain the block’s mass. Fill in the table below.
