The temperature is such that the rms speed of nitrogen molecules is 900. m/s at 750. mm Hg pressure.
 
  If the pressure increases to 780. mm Hg while the temperature remains constant, what is the rms speed now? Molecular weight of nitrogen molecule is 28.

Question 2

A hole of radius 1.0 mm occurs in the bottom of a water storage tank that holds water at a depth of 15 m. At what rate will water flow out of the hole?
 
  What will be an ideal response?

Answer to Question 1

same -- 900. m/s since depends only on temperature

Answer to Question 2

0.053 m3/s
