Chapter 13: Q23PE (page 470)
Convert an absolute pressure of 7 x 105 N/M2 to gauge pressure in lb/in2 (This value was stated to be just less than 90.0 lb/in2 in Example 13.9. Is it?)
Pressure in terms of lb/in2 is 86.95 lb/in2.

Question:The temperature inside a supernova explosion is said to be 2.00×1013 K. (a) What would the average velocity vrms of hydrogen atoms be? (b) What is unreasonable about this velocity? (c) Which premise or assumption is responsible?
Question:Late on an autumn day, the relative humidity is 45.0% and the temperature is 20.0°C. What will the relative humidity be that evening when the temperature has dropped to 10.0°C, assuming constant water vapor density?
Question: Thermal stresses caused by uneven cooling can easily break glass cookware. Explain why Pyrex®, a glass with a small coefficient of linear expansion, is less susceptible.
Confirm that the units of nRT are those of energy for each value of R : (a) 8.31 J/mol K, (b) 1.99 cal/mol K, and (c) 0.0821 L atm/mol K.
Question: A high-pressure gas cylinder contains of toxic gas at a pressure of and a temperature of . Its valve leaks after the cylinder is dropped. The cylinder is cooled to dry ice temperature () to reduce the leak rate and pressure so that it can be safely repaired. (a) What is the final pressure in the tank, assuming a negligible amount of gas leaks while being cooled and that there is no phase change? (b) What is the final pressure if one-tenth of the gas escapes? (c) To what temperature must the tank be cooled to reduce the pressure to (assuming the gas does not change phase and that there is no leakage during cooling)? (d) Does cooling the tank appear to be a practical solution?
