Show that the temperature of the gases along a cylindrical exhaust pipe is given by the following expression: hπ d T − Tw = (To − Tw ) exp − x mC & p where Tw is the wall temperature assumed to be constant along the pipe‚ To is the gas temperature at the inlet to the exhaust pipe‚ h is the convective surface heat transfer coefficient‚ d is the diameter of the pipe‚ m is the mass flow rate of the exhaust gasses‚ Cp is the mean specific heat of the exhaust gasses‚ x is the distance

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

Boyle’s Law Lab Purpose: To determine the relationship between pressure exerted and volume of a gas. Materials: Lab simulation. Procedure: 1. Open animation file 2. Modify the number of books that press down on the piston starting from 0 books and increasing by 1 each time until 19 books. 3. Record the pressure (# of books) and volume for 19 different pressure values. 4. Record those values in a table 5. Using the data‚ plot a graph of pressure in function of volume. Conclusion:

Overview The Bhopal disaster‚ also referred to as the Bhopal gas tragedy‚ was a gas leak incident in India‚ considered the world’s worst industrial disaster.It occurred on the night of 2–3 December 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal‚ Madhya Pradesh. Over 500‚000 people were exposed to methyl isocyanate gas and other chemicals. The toxic substance made its way in and around the shantytowns located near the plant.Estimates vary on the death toll.

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
