A bottle at 21.0C contains an ideal gas at a pressure of 126.4 × 103 Pa. The rubber stopper closing the bottle is removed. The gas expands adiabatically against Pexternal = 101.9 × 103 Pa, and some gas is expelled from the bottle in the process. When P = Pexternal, the stopper is quickly replaced. The gas remaining in the bottle slowly warms up to 21.0oC. What is the final pressure in the bottle for a monatomic gas, for which CV,m = 3/2R, and a diatomic gas, for which CV,m = 5/2R?
What are the annual CO2 emissions based on your vehicle use, vehicle's fuel consumption and a justified general combustion equation? Please use 10,000 miles as a reasonable estimate for annual vehicle use and use a published gas mileage for any sp..
You performed this fractional distillation using an air condenser as the "fractionating" column. Explain why the distillate may have been obtained in higher purity if you would have used a fractionating column packed with glass beads.
At an altitude of 10000 ft, the partial pressure of oxygen in the lungs is about 68 mm Hg. What is the concentration (in mg/L) of dissolved O2 in blood (or water) at this partial pressure and a normal body temperature of 37 degrees C
80.0 of is initially at room temperature 22. a chilled steel rod at 2 is placed in the water. if the final temperature
A reaction that is used to propel rockets is N2O4(l) + 2N2H4(l) --> 3N2(g) + 4H2O(g). This reaction has the advantage that neither product is toxic, so no dangerous pollution is released
