At 36 °C, the average translational kinetic energy of a gas molecule is K. If the temperature is now increased to 89 °C, the average translational kinetic energy of a molecule, in terms of K, will be closest to
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule.R=8.314 J/(mol·K) and ℳ is molar mass in kilograms per mole. Note that a joule is the same as a kg·m2/s2.What is the rms speed of Cl2 molecules at 415 K? What is the rms speed of He atoms at 415 K?

The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the sume kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed 3RT rms speed where R 8.314 J/(mol-K) and M is molar mass in kilograms per mole. Note that a joule is the same as a kilogram-meter squared per second squared (kg-m2/s2) What is the rms speed of O, molecules...
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed 3RT mms speed - VA where R = 8.314 J/mol K) and is molar mass in kilograms per mole. Note that a joule is the same as a kilogram-meter squared per second squared (kgm/s?). What is the rms speed...
