Question

a)Set the temperature to 350 Kelvins (350 K) and select atomic hydrogen

(A = 1)

for gas type. What is the likeliest particle speed (in m/s) to be found in a sample of atomic hydrogen at 350 K?

Double-check that you have set the temperature to 350 K. Have you selected atomic hydrogen

(A = 1)

from the drop-down menu? Are you reading the speed value from the center of the graph? m/s

(b)

Now double the particle mass, by selecting molecular hydrogen

(A = 2)

while leaving the temperature unchanged. What is the new value of

v_max (in m/s)?

Double-check that you have set the temperature to 350 K. Have you selected molecular hydrogen

(A = 2)

from the drop-down menu? Are you reading the speed value from the center of the graph? m/s

(d)

The kinetic energy of an atom or molecule is proportional to the particle's mass and to the square of its speed

KE = 1/2 mv².

Suppose that m = 1 amu for atomic hydrogen (H) and m = 2 amu for molecular hydrogen (H₂). Using the v_max value you measured for atomic hydrogen, what is the likeliest kinetic energy (in amu · (m/s)²) of one hydrogen atom?

...... amu · (m/s)²

^{^e)}

Likewise, calculate the kinetic energy (in amu · (m/s)²) for one molecule of diatomic (two-atom) hydrogen.

...amu · (m/s)²

^{^g)}

Suppose that a particular asteroid has a certain specific escape velocity. Which of the following changes will make it easier for atmospheric gas particles to escape the asteroid's gravity? (Select all that apply.)

...making the atomic mass smaller (less massive gas particles)

...making the temperature higher (hotter gas particles)

...making the atomic mass larger (more massive gas particles)

...making the temperature lower (cooler gas particles)
