purpose of this experiment is to find out the density of the unknown solid object by determining the mass and the volume through the experiment. To do this we will be get the mass of the object and determine the volume of the object by placing it into a liquid. Then we will divide mass by volume and get its density. Materials 3 buckets filled with water Water A bucket to measure volume A stool Measuring scale to measure weight Notebook Procedure 1. Find the weight of the student and then convert

droplets are visible‚ remove them before adding the drying agent. Add a small amount of anhydrous sodium sulfate (or magnesium sulfate) to the flask. Let the mixture stand for 5 min. occasionally swirling it gently. 7) Decant or pipette the organic liquid away from the drying agent and place it in a clean‚ dry Erlenmeyer flask. Place it in the hood to allow the ether to evaporate (if needed‚ set aside overnight to dry). 8) After separating the mix‚ collect the products by vacuum filtration. Wash with

the temperature of the warm water before the ice was add it and after the ice was added it. To take the temperature of the water we need to use a thermometer and make sure it’s in Celsius. To determine the mass‚ first I need to find the mass of the liquid (water) using a graduated cylinder and then find the mass again after the ice is added and then melted using the same material (graduated cylinder).

The investigation was designed to determine the effect of the addition of increasing concentrations of a miscible liquid (ethanol) on the solubility of KNO3 in water. The results of the investigation support the hypothesis that water‚ which exhibits greater polarity‚ is able to dissolve a greater mass of KNO3 at lower temperatures compared to tested concentrations of Ethanol ranging from 12.5% to 30%. Furthermore‚ the results of the graph 1 show correspondence to the dielectric constant of each solvent

Discussion The mucilage glue would work well with paper because the paper would soak up the glue and the wood would have to have a lot of glue and time. The glue stick isn’t that wet so it wouldn’t be soaked up by the wood. The white glue is a liquid so it’s sticky but takes time to dry. VII. Conclusion I was right when I said that mucilage glue is good on paper. I was right also when I said that‚ a glue stick is pretty good on paper. I said that the white glue just needed time to dry‚ so

The reason this homemade lava lamp works is because the tiny droplets of liquid join together to make one big lava like blob. Place a flashlight with a bright beam under the bottle to illuminate the bubbles for maximum visual effect. Soda bottle with cap Vegetable oil  Food coloring any color  Alka -seltzer A cup

“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 water will evaporate to satisfy equilibrium. When this water evaporates‚ heat is taken from the surrounding liquid water which cools it down. In cooling tower design‚ a very important variable is the wet bulb temperature of the air. The wet bulb corresponds to the current humidity of the air. The greater the difference between the air temperature and wet bulb

they made from materials available in nature‚ to make tools and waterproof items. Pitch glue differs from conventional glue that is available in stores today. It has a tar like consistency and molds like putty. The glue must be melted before use if a liquid consistency is desired. Different tribes had their own recipes for making pitch glue‚ where they added ingredients to make the glue more fibrous. Instructions Make Charcoal 1.
