In my experiment I found that the realtivity between densities and temperature corispond to each other. I first found the densities of all 5 liquids.. I first found how much my cylinder that i was going to measure my liquids in weighs. I did this because when i go to measure my other liquids i have subtract the weight of the cylinder to get an accurate measurement for the liquid. I used 10 ml of liquid each time I weighed another liquid. All the liquid densities are displayed in table 1. After I knew my densities I measured out 50 ml of that liquid and put in in the microwave for 2 minutes. I heated up soap for my second liquid and 1 minute in the soap had gone everywhere in the microwave, so after that i put a plate on top of each

To calculate the experimental mass the substance of each bag and the bag its self was measured using a balance. After gathering the mass subtract the mass of the empty bag to the mass of the unknown substance, in order to just have the mass of the substance. Afterward the mass of the unknown substance was divided by the number of moles recorded on the bag of the substance. The measurements are displayed on the table

Fill beaker with water Use the disposable pipette to place water in the graduated cylinder until the unidentified object would be completely submerged in water Record what the measurement of water in milliliters before placing the unidentified object into the graduated cylinder Gently place the unidentified object into the graduated cylinder Record the measurement of the water in milliliters after placing the unidentified object into the graduated cylinder Subtract the measurement of water in milliliters before placing the unidentified object into the graduated cylinder from the measurement of the water in milliliters after placing the unidentified object into the graduated cylinder, this is the volume of the unidentified object Record the volume (the answer you got in step 10) of the unidentified object in the data table Weigh the unidentified object on the scale, this is the mass of the unidentified object Record that number in the data table Calculate the density of the object by dividing the mass by the volume and rounding it to the proper significant figure, Record the density of the unidentified object in the data table Repeat the lab 2 more times and with each experiment record the data in the chart under the correct trial number corresponding with the correct

Characteristic Property- Test 2- Density Materials: Triple Beam balance, distilled water, graduated cylinder, unknown 6 Procedure: first we found the mass of the empty graduated cylinder and then its mass with the now distilled unknown. After subtracting the mass of the graduated cylinder, we were able to find the volume. For every 1mL=1cm³ so there we had the volume found with the graduated cylinder. We divided the mass by the volume in order to get the density Data: We found that the density of our unknown was 0.76 g/cm3.

Our first method was to weigh the glass by putting it in a graduated cylinder of water and placing the glass inside and to observe the lever to with the water rose after first recording the original state of the water. The second test we preformed was to measure the glass and use it’s dimensions to determine the density. This procedure taught me how problem solve effectively and scientifically using information I previously learned in both chemistry and mathematics and applying it to this problem. This also gave me the ability to test the effectiveness of my experiment and decide which one was more proficient at producing an accurate test of the density of the glass. We continuously referred back to the original request of the experiment, making sure our goals aligned with the problem at hand, determining

Volume Lab In this four parted lab the purpose is to use measurement and water displacement and calculations to find the volume of various objects. Part A questions were how much drops of water were needed to make 1mL the original hypothesis made was ten drops however this was proven wrong once the data in which twenty drops of water rose 10 mL of water to 11 mL of water, nineteen to rise from 11 mL to 12 ml, and finally eleven drops of water to rise from twelve mL to thirteen mL. Once the average was calculated which was 16.6 drops, which meant on average that's how much it needed to make one mL. By subtracting from the average with the hypothesis the hypothesis was revealed to be 6.6 drops off. Part B questions were based on water displacement. In which the question was how much was the difference between 20 mL of water and 3 marbles.

In addition, for calculating the mass of the pennies and the unknown substance, zero the balance and place it in the weigh boat to receive the data. Lastly, to calculate the density of the substances, use the formula D=MV, in which dividing the mass by the volume allows to do so. In order to be certain of the data that is collected, running multiple trials could help be accurate. A method to get an average value of the density can be expressed by the formula D1+D22. This formula basically allows one to add the data of all the trials and divide it by the number of trials that was performed.

This heating and cooling was repeated until there was very little (less than 0.0010 grams) fluctuation in numbers. Vial one had a start weight of 14.7681 and an end weight of 15.4098, meaning the mass of the water was 0.4658. Vial 2 had a start weight of 14.7451 and an end weight of 15.3833, meaning the mass of the water in this sample was 0.4633. The mass of the water was found by subtracting the mass of the vial with the hydrate (the start weight) from the mass after the final heating (the final weight). To then find the percent water divide the water mass by the hydrate mass and multiply by 100 since the number is a percent.

I looked over the instructions one last time and decided not to bother with them. It’s not like I couldn’t understand them – they were for a simple 8th grade science experiment, and I was an 8th grader with an interest in science. My problem with them was that they called for me to waste an entire hour moving a single thermometer between several different flasks of water. The different colored flasks were to be heated by an incandescent lightbulb, and the data I was supposed to gather by hand would reveal the exact nature of the relationship between the color of each flask and the amount of energy it absorbed. The concept of the experiment intrigued me, but I just couldn't accept the fact that I would have to manually track the temperature of each flask.

Rediet Legese iLab Week # 6 CRUDE OIL DISTILLATION Introduction: The aim of this week lab experiment is to experiment distill crude oil and to check how temperature determine the chemical properties of crude oil plus how the boiling point can also show physical properties. They are two major finding in this experiment. he first finding was the point at which the raw petroleum is heated to the point of boiling, at 275 0C, the gas and kerosene oil are refined, however the oil (lubricant ) stays as an unrefined feature oil.
