What is the RMS speed of Helium atoms when the temperature of the Helium gas is 448 K? (Possibly useful constants: the atomic mass of Helium is 4.00 AMU, the Atomic Mass Unit is: 1 AMU = 1.66×10-27 kg, Boltzmann's constant is: kB = 1.38×10-23 J/K.) What would be the RMS speed, if the temperature of the Helium gas was doubled?

The surface of the sun has a temperature of about 5800K and consists largely of hydrogen atoms. Find the rms speed of a hydrogen atom at this temperature. (The mass of a single hydrogen atom is 1.67×10−27kg.) The escape speed for a particle to leave the gravitational influence of the sun is given by (2GM/R)1/2, where M is the sun's mass, R its radius, and G the gravitational constant. The sun`s mass is M=1.99×1030kg, its radius R=6.96×108mand G=6.673×10−11N⋅m2/kg2. Calculate the...

6. The average body temperature of a healthy person is 37.0°C. Boltzmann's constant is 1.38 × 10−23 J/K. If a fever increases the temperature to 38.6°C, by what percentage does the average kinetic energy of the molecules increase? 7. In intergalactic space, there is an average of about one hydrogen atom per cubic centimeter and the temperature is 6.10 K. What is the absolute pressure? Boltzmann constant is 1.38 × 10−23 J/K. (answer is in Pa)
A gas bottle contains 4.33×1023 Hydrogen molecules at a temperature of 320 K. What is the thermal energy of the gas? (You might need to know Boltzmann's constant: kB = 1.38×10-23 J/K.)

If temperature were measured in J/molecule (which is what it measures) instead of Kelvin, what would be the value of K, Boltzmann's constant? 2/3 J/K 2/3 1.38 time 10^23 J/K 3/2 J/K
A gas bottle contains 5.58×1023 Nitrogen molecules at a temperature of 380 K. What is the thermal energy of the gas? (You might need to know Boltzmann's constant: kB = 1.38×10-23 J/K.) How much energy is stored in ONE degree of freedom for the whole system? What is the average energy of a single molecule?
14. Using internet searchable data and an assumed exosphere temperature of 200 °K, assess whether you should expect the following gasses in the atmosphere of Titan. Next to each, write either "escapes" or "bound". Assume no replenishment. Remember, a gas can be assumed to escape if the average velocity is greater than 1/6thof the escape velocity. Useful equations: (3 points) 3 2GMT esc Where: k 0.008 amu km/s2 "m" is in terms of the mass of hydrogen (mH), which is...
