Fill in the following table with the appropriate information. Be sure to use SI units. You may need to re-measure your puzzle pieces using a metric ruler. Piece identity Number of cubes Mass (g) Surface area (cm2) Volume (cm3) b. Add Density as the header in the final column of

Density is the degree of consistency measured by the quantity of mass divided by the volume. Buoyancy means the ability for an object to float in water. When talking about density we are trying to figure out how depth the object is in the water or how much water do we need in order for the object be closely deeper to the water. For instance, if we place a ball in the water and it has a mass of 4grams and the water has a volume of 2, the density of the ball placed in the water will be 2 grams per

material and its density?

Introduction A lava lamp (or Astro lamp) is a decorative novelty item, invented by British accountant Edward Craven-Walker in 1963. The lamp contains blobs of colored wax inside a glass vessel filled with clear liquid; the wax rises and falls as its density changes due to heating from an incandescent light bulb underneath the vessel. The appearance of the wax is suggestive of pāhoehoe lava, hence the name. The lamps are designed in a variety of styles and colours. The underlying fluid mechanics phenomenon

Are the Volumes of Pure Substances Additive? Introduction In this lab, the densities and mass of water and isopropyl alcohol were calculated in order to answer the question ‘are the volumes of pure substances additive?’ This lab was used to help introduce the different types of glassware that will be used, as well as basic concepts such as density and the difference between accuracy and precision. Accuracy is how close the measure value is to the true value, while precision is how close the measured

of this experiment was to learn how water displacement affected density. Another objective was to identify the metals used in our experiments. We used a variety of different metals to test their correlation and to find out if it was negative or positive. I did not expect to learn much from this experiment as we had already discussed density in class and learned that water displacement is basically volume so as it increased the density would have decreased had we used metals of the same mass. I will
