full_question: Hemispherical analyzers sort particles based on this quantity, which is equalized for the ions during TOFMS. The equipartition theorem predicts that this quantity's average value for a monatomic ideal gas would be linearly related to the product of the Boltzmann constant and temperature. Classically, momentum squared over twice mass equals--for 10 points--what quantity, which also equals "one-half m v squared?"
