Determine the average kinetic energy of motion of molecules of a monatomic ideal gas at a temperature of T = 200K?
| September 15, 2021 | education
Given: T (absolute temperature of a monatomic ideal gas) = 200 K.
Reference data: k (Boltzmann constant) = 1.38 * 10-23 J / K; i (the number of degrees of freedom of a monatomic gas) = 3.
You can calculate the average kinetic energy of motion of molecules of a monatomic ideal gas using the formula: Ek = i / 2 * k * T.
Let’s make the calculation: Ek = 3/2 * 1.38 * 10-23 * 200 = 414 * 10-23 J.
Answer: According to the calculation, the average kinetic energy of molecules is 414 * 10-23 J.
