Density and Right Hand Corner
Exploring Density
Simulation Exploration: Login to the PHET Website.
A basic property of any homogeneous substance is its density: the ratio of its mass to its volume. The density of a liquid or solid is an intensive property, which means that the density does not vary with the size of the sample but only depends upon its composition. The determination of density is a nondestructive physical process for distinguishing one substance from another.
The mathematical relationship is: Density= massvolume.
Part A: 1. Find the blocks tab in the right hand corner. Click on the “Same Mass” tab. 2. Insert the blocks one at a time in the pool of water. Observe the change in the water level. a. Note: Only 1 block should be in the water at any given time. 3. Completely submerge the blocks that float. Observe the change in the water level.
Calculate the density of each block:
Block | Mass | Volume | Density | Float or Sink | Yellow | 5.00 kg | 10.00 L | 0.5 kg/L | Float | Blue | 5.00 kg | 5.00 L | 1 kg/L | Sink | Green | 5.00 kg | 2.50 L | 2 kg/L | Sink | Red | 5.00 kg | 1.25 L | 4 kg/L | Sink |
Part B: 1. Find the blocks tab in the right hand corner. Click on the “Same Volume” tab. 2. Insert the blocks one at a time in the pool of water. Observe the change in the water level. a. Note: Only 1 block should be in the water at any given time. 3. Completely submerge the blocks that float. Observe the change in the water level.
Block | Mass | Volume | Density | Float or Sink | Yellow | 8.00 kg | 5 L | 1.6 kg/L | Sink | Blue | 6.00 kg | 5 L | 1.2 kg/L | Sink | Green | 4.00 kg | 5 L | 0.8 kg/L | Float | Red | 2.00 kg | 5 L | 2.5 kg/L | Float |
Part C: 1. Use the scale and the pool to determine the density of each of the blocks. Block | Mass | Volume | Density | Float or Sink | AGold | 65.14 kg | 3.38 L | 19.3 kg/L | Sinks | BApple | 0.64 kg | 1.00 L | 0.64 kg/L | Float | CGasoline | 4.08
