If the rms speed of the molecules of a quantity of helium at temperature 142 K is the same as the rms speed of neon atoms at a second temperature, what is the temperature of the neon gas? Answer in Kelvins. The answer is NOT 710, 713.55 or 284.
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?
The rms speed of the molecules in 2.0 g of hydrogen gas is 1800 m/s. What is the total translational kinetic energy of the gas molecules? ________kJ Answer not 1.62kJ What is the thermal energy of the gas? __5.4kJ___ <----That is the right answer. 500 J of work are done to compress the gas while, in the same process, 1400 J of heat energy are transferred from the gas to the environment. Afterward, what is the rms speed of the...
