AN IDEAL GAS
1. The particles in two samples of different gases, nitrogen and hydrogen, have the same average
speeds. Which of the two samples has the greater temperature? Explain.
2. Two tanks containing an equal number of moles of an
ideal gas are at equal temperatures. The volume of
tank F is greater than the volume of tank E.

a. Is the average speed of the particles in tank E
greater than, less than, or equal to the average speed
of the particles in tank F? Explain.

Tank F
b. Is the average change in momentum of one gas particle in a single collision with a wall in
tank E greater than, less than, or equal to the average change in momentum of one particle in
a single collision with a wall in tank F? Explain.
c. On average, will a single particle collide with a wall in tank E more often than, less often
than, or as often as in tank F? Explain.
Is the number of particles colliding with a wall per unit time and unit area in tank E
greater than, less than, or equal to the number of particles colliding with a wall per unit time
and unit area in tank D? Explain. (Hint: Compare the number of collisions each second in
the two tanks and the surface area of the walls of each tank.)
d. Use your answers to parts b and c above to predict whether the pressure in tank E is greater
than, less than, or equal to the pressure in tank F. Explain.
Is your answer consistent with the ideal gas law?
