Visit this PhET density simulation (http://openstaxcollege.org/l/16phetmasvolden) and selectMystery Blocks.(a) Pick one of the Mystery Blocks and determine its mass, volume, density, and its likely identity.(b) Pick a different Mystery Block and determine its mass, volume, density, and its likely identity.(c) Order the Mystery Blocks from least dense to most dense. Explain.
Use the Density interactive to place the densities of the objects from highest to lowest.
Wood 79.170g scale /279.2mL in water
Lead 47.460g scale/204.2mL in water
Mystery 37.380g scale/204.2mL in water
I placed the higest density to lowest density:
Wood
Lead
Mystery
It came out incorrect, stating: You do not have the highest density object at the top. Remember that density is the mass per unit volume. To get the volume, you need to subtract the initial volume of the water in the graduated cylinder from the final volume after the object is fully submerged.Note: The inital volume of water is 200.0mL
An object floats in water if it less dense than water. In other words if the volume of the material weighs less than the same volume of water (for example a piece of plastic). An object sinks in water if it is more dense than water (for example a piece of steel). The same principle applies for objects surrounded by air. Objects that are less dense than air, i.e., weigh less than the same volume of air, will float upward. For example, a helium-filled balloon floats upward because the helium inside the balloon weighs less than the same volume of air, since helium molecules weigh less than the nitrogen and oxygen that make up most of our atmosphere. Objects that are more dense than air, like humans, sink to the bottom of the atmosphere.
Suppose we put some air in a sealed, flexible container like a balloon. No air can enter or leave the container, but since the container is flexible, it can easily change its size or volume. At first, the air temperature, air number density, and air…
