Problem
- A flask of volume 300.0×10−6 m3 contains air at a pressure of 5.00×105 Pa and a temperature of 27.0∘C . The flask loses molecules at a rate of 3.00×1019 per second. Estimate how long it takes for the pressure in the flask to fall to half its original value. (Assume that the temperature of the air remains constant during this time.)
