Up in Smoke

PERFORMANCE GOALS

1. To compare the amount of solid contained in first-hand and second-hand smoke. 2. To examine the solids that are deposited in the lungs

when smoking. 3. To examine the efficacy of a filter in removing

solids from cigarette smoke. 4. Calculation of percent.

Equipment List (just so that you know how we did the experiment and what was used)

1 – Filtered cigarette 1 – Unfiltered cigarette 1 – Mini cigar 1 – balance 1 – filter paper 2 – 500 mL filter flasks 2 – funnels 1 – rubber hoses 1 – 1 hole stopper

FOR THIS EXPERIMENT, YOU DO NOT HAVE TO DO THE ACTUAL LAB.

YOU JUST NEED TO WATCH THE VIDEO, READ THIS DOCUMENT COMPLETELY AND USE THE INFORMATION PROVIDED TO COMPLETE THE LAB. You may need to read the document and watch the video multiple times for this to make sense. Please start early and email the TAs to ask questions. Please remember to copy Dr. Swamy on all your Canvas messages (emails within Canvas) to the TAs.

This information is being provided so that you can use this to understand how we got the data for the observations provided and synthesize all the information to draw conclusions for the experiment. PROCEDURE - Gathering Data

1. Obtain two sheets of filter paper and label them on the edge as #1 and #2. Weigh each

piece of filter paper and record the weight in Data Table I. 2. Set up an apparatus as shown in the diagram below. Ask your instructor to verify

the connections. Attach the suction flask to the vacuum line. Be very careful attaching and removing the vacuum line from the side arm flasks. Do NOT simply tug on the hose to remove it as this can break the top of the flask off. A twisting motion will remove the hose.

3. Weigh an unfiltered cigarette and record the weight in Data Table I.

4. Clamp the cigarette funnel pointing up and the second hand smoke funnel about a half-inch

above to allow air to go in. 5. Turn on both vacuum valves slightly and light the cigarette. Try to mimic a smoker by

turning the vacuum on the cigarette side on and off several times. Do not turn the second- hand smoke vacuum line off. Adjust the vacuum so that the cigarette burns in 3-5 minutes.

6. When the cigarette has burned down to the last centimeter, turn off the vacuum and put out

the cigarette. 7. Carefully remove both filter papers and weigh them. Record the weight of each filter

paper in Data Table I. 8. Gently, knock the ash off of the cigarette and weigh the un-burned portion of the cigarette.

Record the weight in Data Table I.

9. Repeat the experiment for a filtered cigarette and for a “little cigar.”

Procedure and Observations write up

Today, we will be examining the amount of smoke created by various tobacco products and comparing how much of that smoke is going to the smoker, and how much ends up as second hand smoke. Please refer to the picture below for the experimental set up. In the very center, there is a Cigarette being held in a funnel. When the cigarette is lit, two vacuums will be turned on. The first vacuum is on the right side of the picture, and the second vacuum is on the left side of the picture. The purpose of the vacuums is to draw the cigarette smoke towards two different paths.

The first path, which is First Hand Smoke, starts from the cigarette, travels down in to the

funnel/tubing and towards the flask on the right. Before the flask there is a piece of filter paper that is collecting the cigarette smoke while allowing air to pass through. The second path, which is Second Hand Smoke, starts from the top of the cigarette, travels up in to the funnel/tubing and towards the flask on the left. Once again, there is a filter paper right before the flask to collect the cigarette smoke.

After a cigarette was completely burned, the amount of smoke collected on the filter paper was

weighed, and then compared to the other filter paper. Additionally, the cigarette was weight before and after being burnt, to determine how much mass was lost due to the burning process. This experiment was done for a filtered cigarette, unfiltered cigarette, and a slim cigar.

The Data Table below was created based off of the results of the three trials. Please make a data table of your own to complete.

Using the data provided, you will now have to calculate the mass of solid that was collected on each filter paper, both first and second hand smoke, for each of the tobacco products. Next, you will calculate the mass of the cigarette that was consumed during the experiment. In the bottom row, you will calculate the milligrams of solid collected per gram of cigarette consumed to determine which of the tobacco products released the greatest ratio of first hand smoke to second hand smoke. Think about which of these tobacco products poses the greatest health risk to the smoker, was well as the people around them that are inhaling the second hand smoke.
