<p> A Charles’ Law Experiment Information & General Instructions</p><p>1. We cannot measure the changes in volume directly, so we will use a line drawn on the balloon to see what happens to the length of the line as the air in the test tube changes temperature.</p><p>2. You need to draw a picture (on your own paper) showing the molecules inside the test tube at room temperature and after the test tube is cooled.</p><p>2 cm line 3. Write the following question on your paper. “How does a change in temperature affect the volume of a quantity of gas?”</p><p>4. Write your hypothesis in the Hypothesis section. Note: You may not revise your hypothesis once you have written it on your paper.</p><p>5. Work together with your partner to plan the steps for your investigation. Read the note below then print the steps for your procedure in the sequence boxes.</p><p>Note: Here are some things you must incorporate into your procedure: Note: Shorten these up! Don’t try to copy the whole sentence to the box.</p><p>. Inflate the balloon a couple of times before drawing the line. . Draw a 2 cm line on the balloon. . Draw little perpendicular lines on each end of the 2 cm line. . The test tube must be cooled in ice water for at least a minute before the balloon is attached to the test tube. . The test tube must be submerged in the ice-water up to the top of the test tube or as close as you can get it. . The test tube must be held down by one person to keep it from popping up when the water is poured in with the ice. . The test tube must be submerged in each bath for at least 1 minute.</p><p>6. You are expected to revise your procedure (if necessary) during the experiment so that your written procedure matches what you are actually doing.</p><p>7. Remember to repeat your procedure twice (do the experiment twice).</p><p>8. Record your observations and data on your own paper. Label everything!</p><p>9. REMEMBER... you must repeat your procedure to collect a second set of data to confirm your observations.</p><p>10. Get a lab sheet from your teacher and copy the question, your hypothesis, and the final version of your procedure to the appropriate sections of the lab sheet.</p><p>11. In the Data section of the lab sheet, construct a table to display your data.</p><p>0f4916160371723285b61624f1b1df0a.doc 4／4／2018 Charles’ Law Lab Hypothesis Page</p><p>The Question</p><p>Our Procedure (Numbered steps, please!)</p><p>0f4916160371723285b61624f1b1df0a.doc 4／4／2018</p><p>Please continue on the other side.
