measurements. With this lab we had to understand how to analyze the data using measurement bounds. Theory: In this experiment we were to find the density of the wood we are measuring by using the method of upper bound and lower bound. Density is a physical property of matter. Every element and compound has its very own unique density associated with it. Density can be defined in a qualitative manner as the measure of the relative heaviness of objects with a constant volume or also as the amount per unit

Cartesian Diver Essay The Cartesian Diver is named after the French scientist Rene Descartes. This experiment is supposed to show buoyancy‚ density and different forms of matter at work‚ when demonstrated. To create the Cartesian Diver‚ you’ll simply need: • A empty plastic bottle • A plastic eye dropper • Water 1. Fill the bottle with water‚ but be cautious of spills. 2. Very carefully‚ drop the dropper inside the bottle. Then‚ seal the cap on very tightly. 3. Squeeze the bottle‚ but not too

mass of the liquid‚ which was 14.21g per mole. The next part was used to determine the density of the volatile liquid. First the volatile liquid was placed in a pyncometer and massed; water was then placed in the same (now clean and empty) pyncometer and massed. The density equation was manipulated using the data for water to solve for the mL of the capillary tube. This new information was used to find the density of the liquid‚ which was 1.33g/mL. The last part of the experiment was used to determine

the results of the experiment themselves‚ whether volume‚ mass‚ or density‚ proved insufficient in my attempts to distinguish the identities of the metals. Thus‚ during the experiment‚ I also observed the color of the metals‚ and used these observations in my assessment of the metals. The five trials for the golden metal produced an average density for all trials of 8.34 grams per cubic centimeter. [Processed Data Table: Density of the Golden Metal]. The golden metal itself‚ while referred to as
