Physics Density Investigation

Extracts from this document...

Introduction

Physics Density Investigation Density * Aim: we will measure the density of two objects, a microscopic slide and a glass stopper, to decide whether they are both from the same material or no. * Hypothesis: materials have different densities, and the two objects we have are to be tested to know if they have similar densities so to know if they are made of the same material, and my prediction that they are both made from the same material, which is said to be glass. * Variables: volume and mass. ...read more.

-Glass stopper: 1.Place the glass stopper in the displacement vessel and put the water that is displaced in the measuring cylinder and take the reading, which is the volume. 2. Find out the mass of the glass stopper using the digital balance and write it down. * Data collection: Table (1): measurement of the microscopic slide. Width (W) �0.0025 cm Length (L) �0.0025 cm Thickness (T) �0.0005 Mass (M) �0.005g Microscopic slide 2.54cm 7.5cm 0.095cm 4.43g Table (2): measurement of the glass stopper. Volume (V) �0.25 cm� Mass (M) ...read more.

Conclusion

The glass stopper had some air bubbles in it. 3. Uncertainty in measuring the irregular shape (glass stopper) using the displacement vessel. 4. The glass stopper was weighted after we took it of from the water, so it had water sticked to it. * Improvements: 1. To avoid insufficient reading we should take three readings for three different students and find there average and use it. 2. Avoid glass stoppers that have air bubbles in them, because it increases the risk of uncertainty and wrong answers. 3. Use the measuring cylinder directly with ther irregular shapes (glass stopper). 4. Weight the object before placing it in the water. ...read more.

  1. Create and sell an accessory collection (starting a small business)

    now I can do less with the same amount of money, materials raised 350% comparing to the past yea, with all the default problem, so it is really difficult to buy the same peaces of material I bought before with the same price or less charged as possible.

  2. The Evidential Value of Glass Fragments.

    > Activity - If a person is very active then a lot of glass fragments will be lost early on after the incident but if they have rested after the incident then most particles of glass should persist. > Texture - Varying materials will depend on how well glass fragments can persist upon them.

  2. Investigation into the physical properties of glass.

    This cools the surface but leaves the middle hot. When the middle cools it contracts, the surface contracts with it, meaning that the surface has contracted twice and is now under compression. To break the glass this compression must first be overcome.
