Which would have the lower average molecular speed?
(i) a sample of hydrogen gas, H2, at 0C
(ii) a sample of oxygen gas, O2, at 100C
1.(i)
2.(ii)
3.They have the same average molecular speed.
4.It is impossible to tell.
Question 2Assume that the average speed for the molecules within a sample of gas is 150 m/s. What would be possible values for the root-mean-square and most-probable speeds?
1. vrms = 162 m/s, vmp = 132 m/s
2. vrms = 132 m/s, vmp = 162 m/s
3. vrms = 150 m/s, vmp = 150 m/s
4. vrms = 182 m/s, vmp = 162 m/s
