what is the difference between avg kinetic energy and root mean square velocity?
Asked by n jain | 17 Mar, 2011, 12:00: AM
answered-by-expert Expert Answer
Dear student,
 
Root mean square velocity: The square root of the average of the squares of the individual velocities of the gas particles in a mixture. To put it in a simpler way , it's the average of how fast the particles in a gas are going (assuming you ignore the direction they're traveling in).
 
 
Average kinetic energy: 
  • kinetic energy of one molecule: ½ mv2
  • average kinetic energy of one mole of molecules ½ M(vrms)2 = (3/2) RT
  • average molecular kinetic energy depends only on temperature for ideal gases

Hope this helps.

Thankyou
