16 G.C.2-2 Investigation of the Relationship between Volume and Temperature G. C. 2-2: LABORATORY REPORT CONSIDERATIONS FOR DISCUSSION AND CONCLUSIONS SECTION: As you wri questions you should sion hando te your discussion and conclusions paragraphs in your lab notebook, here are some tips and should be answering. (This is in addition to the "Guidelines for a good discussion and conclu- out provided to you at your first lab class.) hat is your experimental relationship between temperature and volume? Was it direct or indirect? How/why did you determine this? (i.e.. using your graph drawn). - Does the relationship between volume and temperature you determined comply with discoveries made by Charles? Explain why or why not. Why did you have to calculate volume of dry, cold air instead of using the obtained volume of wet. cold air? - Using your understanding of Charles' law and the experimental data obtained, explain what is happen- - ing to the gas at a molecular level when there is a change in temperature.

Explanation / Answer

For liquids or Solutions, As the Temperature increases Volume of Solution decreases, So they are indirectly proportional to each other.

For Gases, As the Temperature increases Volume of the gas increases, So they are directly proportional to each other.

According to Charles, Volume of the given mass of gas is directly proportional to its temperature at constant pressure.

Volume of dry and Cold Air are different because it is affected by temperature, In dry air volume of moisture of other atmospheric gases are absent but in cold air they are present .

As the change in temperature of gas, change volume of gas depending on increases or decreases.
