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 internal energy of an ideal gas depends on A) its pressure. B) its temperature. C) its temperature, pressure, and volume. D) its temperature and pressure. E) its volume.

For a hydrogen gas at 25 degree Celsius, most molecules would be travelling at: A. 2.3 km/sec B. 2.0 km/sec C. 1.8 km/sec D. 1.6 km/sec

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

The atomic mass of neon is 20.2_g/mol, and the ideal gas constant is R = 8.314.J/mol K. The mass of the neon gas is closest to

P1. Consider a gas of oxygen atoms (H0, = 32 g/mol). What should the temperature of the gas be for the mean square speed of the atoms to be v = 100 m/s? While keeping the temperature the same as before, what should the pressure of the gas be for a container of volume V = 51 to be able to contain m = 1 kg of oxygen? How much does the temperature of the gas increase if the container is dropped on the ground at a speed of u = 2 m/s? You may neglect thermal conduction with the outside.
