Lab 12: Gases

For case 1(volume vs. pressure), we set the constant as the temperature and raised or lowered the volume. For case 2(volume vs. temperature), we set the pressure as the constant and pumped in the volume. The  volume adjusted by itself. For case 3(pressure vs. temperature), we set the volume as the constant and adjusted the temperature. The temperature remained at a constant 100 degrees Celsius or 200 K. From this, we measured the pressure. For case 4(number of particles vs. volume), we set the pressure as the constant. Then, we added the number of particles. We increased the number of particles by 20 for each trial.

Questions

3. 

4. a. Bicycle tires seem more flat in the winter because of Charles Law. Charles Law states that as the temperature decreases, the volume also decreases. Hence, since the temperature decreases during the winter, the volume of the gas particles in the tires will decrease making them seem more flat during the winter.

    b. A soda can will explode due to Gay-Lussac's Law. Gay-Lussac's Law states that as the temperature increases, the pressure also increases. Hence, when the soda can is left under the hot sun, the pressure increases which would make it explode.

   c. The pressure will decrease as the temperature decreases due to Gay-Lussac's Law. The rigid container will have a constant volume as a rigid container does not get bigger nor smaller.

   d. No, it would make it worse since the pressure is one of the main factors which is causing the pain. due to Gay-Lussac's Law, as the temperature increases, the pressure will also increase, making it more painful.
