The RMS speed of oxygen molecules in a gas is V. If the temperature is doubled and the oxygen molecules dissociated into oxygen atoms, the RMS speed will become
Options:
Answer:
C
Solution:
urms = √(3RT/M). After the change, T' = 2T and the mass per mole halves (O2 → O), so M' = M/2. Then u' = √(3R(2T)/(M/2)) = √(4 · 3RT/M) = 2√(3RT/M) = 2V. Confirms Ans (c) 2V.
