What is the average kinetic energy of thermal motions of particles in a gas cloud, the temperature of which is 2 x 10 ^ 7 K?
Initial data: T (temperature of particles in a gas cloud) = 2 * 10 ^ 7 K.
Reference data: k (Boltzmann’s constant) = 1.38 * 10 ^ -23 J / K.
The kinetic energy of the thermal motion of a particle in a gas cloud can be calculated by the formula: Ek = 3/2 * k * T.
Let’s make a calculation: Ek = 3/2 * 1.38 * 10 ^ -23 * 2 * 10 ^ 7 = 414 * 10 ^ -18 J = 414 aJ.
Answer: The kinetic energy of a particle in a gas cloud is 414 aJ.
