Question

Be sure to answer all parts.
 
Three 9−L flasks, fixed with pressure gauges and small valves, each contain 8 g of gas at 275 K. Flask A contains CH4, flask B contains H2, and flask C contains He. Rank the flask contents in terms of:

(a) pressure.

  • A > B > C
     
  • A > C > B
     
  • B > C > A  
  • B > A > C
  • C > B > A
  • C > A > B
  • A = B = C

b) average molecular kinetic energy.

  • A > B > C
  • A > C > C
  • B > C > A  
  • B > A > C
  • C > B > A
  • C > A > B
  • A = B = C

c) diffusion rate after valve is opened.

  • A > B > C
  • A > C > C
  • B > C > A  
  • B > A > C
  • C > B > A
  • C > A > B
  • A = B = C

 d) total kinetic energy of the molecules.

  • A > B > C
  • A > C > C
  • B > C > A  
  • B > A > C
  • C > B > A
  • C > A > B
  • A = B = C

e) density.

  • A > B > C
  • A > C > C
  • B > C > A  
  • B > A > C
  • C > B > A
  • C > A > B
  • A = B = C

f) collision frequency.

  • A > B > C
  • A > C > C
  • B > C > A  
  • B > A > C
  • C > B > A
  • C > A > B
  • A = B = C
