If temperature were measured in J/molecule (which is what it measures) instead of Kelvin, what would...
Jupiter's exosphere has a temperature of about 900.0 K. What is the thermal speed of hydrogen (in km/s) in Jupiter's exosphere? The mass of a hydrogen atom is 1.67 x 10-27 kg and Boltzmann's constant is k = 1.38 × 10-23 Joule/Kelvin.
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?
A gas bottle contains 7.54×1023 Oxygen molecules at a temperature of 360.0 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? On average how much energy is stored by ONE degree of freedom for ONE single molecule?
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?
What is the RMS speed of Helium atoms when the temperature of the Helium gas is 412.0 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?
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.
