    1) Explain why alveolar gas has a different composition from air. Atmospheric (external) air contains a high percentage of oxygen and nitrogen whereas alveoli gas contains a lower percentage of oxygen and a higher percentage of carbon dioxide. The differences in composition are due to the fact that gaseous exchange is taking place within the alveoli in the lungs. Oxygen is diffusing from the alveoli into the pulmonary artery and carbon dioxide is diffusing back into the alveoli from the pulmonary

    Kinetic energy is increasing between letters A-B‚ C-D and E-F. Based off the observations‚ in phase A-B Tert-Butyl Alcohol stays a solid‚ in phase C-D Tert-Butyl Alcohol stays a liquid‚ and in phase E-F the chemical stays a gas. This is observed at the particle level because temperature is a measure of Ek; the temperature is increasing which increases kinetic energy. Since Ek is the energy of motion‚ the particles would increase their velocity and the number and force of collisions. However‚ the

    point of the Isopropyl alcohol was similar‚ even though melting point and boiling point were totally different physical properties each other. When I kept water boiling up to 105˚C with the acetamide‚ it maintained a liquid state‚ not turning into gas. Through this‚ I also could deduce the boiling point of acetamide might be much higher than the Isopropyl alcohol‚ and water. In this experiment‚ handling experiment tools such as capillary tubes and small amount of chemicals was a great challenge

    everything around us (anything that takes up space – living or nonliving) and is most commonly in three states (solid‚ liquid and gas). By examining the objects‚ students learn that the book is a solid (in the form of molecules is tightly bound)‚ the water is a liquid (the molecules are close together and moving loosely past one another)‚ and the balloon contains a gas. Students manipulate the oobleck and learn that it does not follow one state of matter (it is a Non-Newtonian substance). By observing
