The temperature of the diatomic hydrogen gas sample is increased to 100 degrees Celsius. The root mean square speed vrms for diatomic hydrogen at 100 degrees Celsius is: A. 4000 m/s B. 2800 m/s C. 2000 m/s D. 1400 m/s E. 1000 m/s F. None of the above

If you launch a projectile upward with a high enough speed, its kinetic energy is sufficient to allow it to escape the earth’s gravity— it will go up and not come back down. Given enough time, hydrogen and helium gas atoms in the earth’s atmosphere will escape, so these elements are not present in our atmosphere. Explain why hydrogen and helium atoms have the necessary speed to escape but why other elements, such as oxygen and nitrogen, do not.

The temperature of a gas is a measure of: a. the size of the molecules of the gas b. the average distance between the gas molecules c. the average potential energy of the gas molecules d. the average kinetic energy of the gas molecules

Explain why the Moon and Mercury possess only very weak, transient atmospheres consisting of constituents temporarily captured from the solar wind or released by collisions with interplanetary debris.
