water‚ at this point the water is dense enough for the egg to float. To find the density of salt water first measured the mass of salt water after adding salt into 800ml of water. The following results are the density of salt water every time increasing 1 table spoon of salt into 800ml fresh water. One table spoon of salt is also equal to 10g.

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

Introduction: In industry‚ a heat exchanger is used to cool down streams for temperature sensitive processes. The now hot cooling water is useless to the plant unless something is done to cool it down. In industry‚ cooling water towers are used to bring the water back down to a sufficient level . In a cooling tower‚ outside atmospheric air is flowed through a “column” while the hot water sprayed into the system. Since air is never at full saturation of water (unless it is raining)‚ some of the hot
