Gas Porosity Lab Report

1. Carefully measure the volume of the trapped gas using the graduations (markings) on the side of the container.

The purpose of this lab was to determine the effect of temperature on the volume of gas when the pressure is consistent and to verify Charles’ Law. The data from the experiment reveals that as temperature increases, so does volume. This also indicates that as temperature decreases, the volume decreases as well.

5. Zoom Out by clicking on the green arrow next to the Save button. Click on the Stockroom and then on the Clipboard and select Balloon Experiment N2. Again, set the temperature, pressure, and moles to 298 K, 1.00 atm, and 0.300 moles, respectively. You may have to click on the Units button to change some of the variables to the correct units. Repeat the experiment with this gas labeling the data link ‘Real Gas N2.’

To calculate the effective diameter of the particles, we use Equation 1 provided below. To determine the effective diameter of the particles, we needed to have the hydrometer readings and temperature for each time taken, as well as using the Coefficient of temperature adjustment table provided in Appendix 3 and the Hydrometer 152H length readings in Appendix 4. To able to determine the Percent Finer for Hydrometer, we use Equation 2 provided below as well as Equation 3 for the Dry Weight of Soil provided below. For Equation 2, we also need the Specific Gravity correction for percent finer table to be able to solve Equation 2. The Specific Gravity correction for percent finer table is provided in Appendix 5. Furthermore, to determine the total

In the fourth stage of this experiment, the density of a gas was determined. A 250ml flask was weighed with an empty rubber balloon and the mass was recorded.

Prepare laptop computer to collect data through Logger Pro software. Open file “06B Enzyme (Pressure)” from Biology with Vernier folder in Logger Pro, and connect the gas pressure sensor to the computer using the USB port. Once Logger Pro is set up, connect the Gas Pressure Sensor to the plastic tubing through the valve on the sensor.

AP Chemistry Mrs. Johnson Chemistry Butane and Inquiry Lab Submitted By Germaine Washington September 30, 2016 Abstract The purpose of these experiments was to determine the validity of the Ideal Gas Law. In the first experiment we used a Butane lighter to conduct a collection of C4H10 gas over water, with which we would measure the volume of the butane produced. It was found the 0.16 g of Butane gas at 299°K and 1.005 atm held a volume of 100mL. The results supported the Ideal Gas Law, PV = nRT.

We measured initially 5.7 grams of a Magnesium Sulfate Hydrate and 7.7 grams of a Zinc Sulfate Hydrate after subtracting the mass of the empty crucible.

Leticia Glass Introduction to Chemistry Lab 4: Properties of Matter: Density Pre-lab Questions: 1. What can cause the density of the same substance to change? Temperature can cause the density of the same substance to change. I also believe the different substances can change because they are either higher or lower in density. Ethanol has a lower density than water, and water has a lower density than calcium chloride.

Use 25 pipette filler by attaching a 25 ml tube, pulling up the water by pushing the button on the pipet to make it go up to 25 ml and let go of the button.

In this experiment, we will collect data from the sample and use the Ideal Gas Law:

The first test performed was the density test. The measured was of the sample was 14.51 grams, and the volume was 20 cm3.

The Accuracy of our results were (109.71 %, 113.57 %) for the sample and its duplicate pH and both of them were within the EPA standard limits and (1.38 %, 1.44 %) for the sample and its duplicate conductivity and both of them they were not within the EPA standard limits.

The objective of this lab experiment is to measure the material in the gas phase and to see how the ideal gas experiment could apply to the physical. In this the material we used was, a sip-lock plastic bag, a large plastic beaker, thermometry, dry ice, water, and butane lighter.
