The molecules in a tank of hydrogen have the same rms speed as the molecules in

Question

The molecules in a tank of hydrogen have the same rms speed as the molecules in a tank of oxygen. State whether each of the following statements is true, false, or unknowable with the given information:

Part A

the pressures are the same

the pressures are the same

unknowable

Part B

the hydrogen is at the higher temperature

the hydrogen is at the higher temperature

Part C

the hydrogen has the higher pressure

the hydrogen has the higher pressure

unknowable

Part D

the temperatures are the same

the temperatures are the same

unknowable

Part E

the oxygen is at the higher temperature

the oxygen is at the higher temperature

unknowable

Explanation / Answer

A. Unknowable

B. False

C. Unknowable

D. True

E. False

RMS speed = (3RT/M)1/2. So RMS speed is directly proportional to temperature and inversely proportional to mass.
