What is the root mean square speed of an As4 particle as it is sublimed? (Assumed at high temperatures arsenic acts like an ideal gas; the Boltzmann constant, kb, can be approximated as 1.4 x 10^-23 KxK-1) and the kinetic energy of the gas is equal to 3/2 kb T. 270 m//s (1/2 kB x T) = 1/2 mv^2 - topic: Energy
