Suppose that the root-mean-square velocity Urms of water molecules (molecular mass is equal to 18.0 g/mol) in a flame is found to be 1.33 x 10' m/s. @Macmillan Learning The Boltzmann constant is k = 1.38 x 10 2 J/K. Avogadro's number is NA = 6.022 x 10 molt What is the temperature T of the water molecules? T K TOOLS
