Question

The rms (root-mean-square) speed of a diatomic hydrogen molecule at 50∘C is 2000 m/s. Note that 1.0 mol of diatomic hydrogen at 50∘C has a total translational kinetic energy of 4000 J.

Part B

The total translational kinetic energy of 1.0 mole of diatomic oxygen at 50∘C is:

Choose the correct total translational kinetic energy.

View Available Hint(s)

Choose the correct total translational kinetic energy.

(16)(4000J)=64000J

(4)(4000J)=16000J

4000J

(14)(4000J)=1000J

(116)(4000J)=150J

none of the above

Part C

The temperature of the diatomic hydrogen gas sample is increased to 100∘C. The root-mean-square speed vrms for diatomic hydrogen at 100∘C is:

Choose the correct vrms.

Choose the correct .

(2)(2000m/s)=4000m/s

(2√)(2000m/s)=2800m/s

2000m/s

(12√)(2000m/s)=1400m/s

(12)(2000m/s)=1000m/s
