we can consider the root mean quadratic speed of a molecule of a gas, which is given by the subsequent formula: \[\Large {v_{RMQ}} = \sqrt {\frac{{3RT}}{M}} \]

where R is the gas constant, namely R=8.31 J/Kelvin, and M is the molecular mass of our gas. T is the gas temperature of course, measured in Kelvin

okay! so how can we figure out which object (A,B,C or D) moves the fastest? what do we plug in?
Michele_Laino
  • Michele_Laino
I think that we can consider only the temperature, since the molecular mass of those gases are similar each other

  • Michele_Laino
namely, we have: \[\Large {M_A} \simeq {M_B} \simeq {M_C} \simeq {M_D}\]

okay!! so 3*temperature? would that mean object D moves the fastest since the solution would be the largest?
Michele_Laino
  • Michele_Laino
yes! that's right!
