Behavior of Gases and Absolute Zero Determination Essay

10) The tape was used to measure gas accumulation in the balloon after 1minute. Measurement and qualitative observations were recorded.

B. How does this graph illustrate Boyle’s law? As more pressure is added the volume decreases and the graph shows this because it is decreasing as well. _________________________________

Please Note: This lab involves a lot of waiting for the gas collection. Make sure you allot yourself the full three hours to perform the experiments.

2. Read and record the temperature of the gas using the thermometer attached to the container.

To start this experiment, set up the gas collecting apparatus. To start Part A, add approximately 15mL of distilled water to the test tube and record the temperature. Use about half of an Alka-Seltzer® tablet and record the mass. Close the test tube with the stopper with the tubing and tilt the test tube so the water and tablet react. When the reaction is finished, record the volume of CO2 recovered by lining the meniscus of the graduated cylinder up with the water level.

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.’

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.

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

I chose this article based on its relevance to my topic and the highlights on new measures that use technology to measure the temperature and pressure

8.When the reaction is completed, record the volume of gas in the graduated cylinder. Record observations about which reactant was the limiting reactant.

1. Start Virtual ChemLab and select Boyle’s Law: Pressure and Volume from the list of assignments. The lab will open in the Gases laboratory.

9. The little man was dragged inwards 1nm, waiting for the temperature to get back to 300 K. The volume and pressure readings were recorded. 10. Readings were continually taken as done in (9), the volume and pressure was recorded each time.

Pressure vs. Number of Particles Lab Report Introduction: The experiment deals with many different parts and one of them is gas, a substance that moves freel through the air and their particles are stread farther away from each other when compared to the other states of matter. The difference between the states of matter are how close the particles are to each other. The experiment was completed to find how pressure affects the number of particles. Pressure, which is the force exerted on an object by physical contact, was used to apply force into the pressure sensor.

Objectives: The main objective of this lab was to determine the relationship between the volume and pressure when the temperature and number of molecules remains the same throughout. Other minor objectives of

This chapter will explain the result and analysis data obtain from the two different experiments. The temperature measurement experiment will determine the decreasing of temperature and comparison between outside and inside room temperature within conditions.
