Question

В сосуде находится газ при температуре 273 К. Определите среднюю кинетическую энергию хаотического движения молекул газа.

Answer 1

T = 273 К

________

Ek - ?

 

Ek = 3/2 * kT

Ek = 3/2 * 1.38*10^-23 Дж/К * 273 К = 5,65*10^-21 Дж

Answer 2

Calculation of Average Kinetic Energy

To determine the average kinetic energy of the gas molecules, we can use the formula:

Average Kinetic Energy (E) = (3/2) * k * T

Where: - E is the average kinetic energy - k is the Boltzmann constant (1.38 x 10^-23 J/K) - T is the temperature in Kelvin (273 K in this case) Substituting the values into the formula, we get:

E = (3/2) * (1.38 x 10^-23 J/K) * 273 K

Calculating this expression gives us the average kinetic energy of the gas molecules.
