Газ содержится под давлением 40 КПа. Концентрация молекул этого газа при указанном давлении составляет 3*10²⁵м³. Какова средняя кинетическая энергия молекул этого газа
The average kinetic energy of the gas molecules can be calculated using the formula KE_avg = (3/2) * k * T, where k is the Boltzmann constant (1.38 * 10^-23 J/K) and T is the absolute temperature (in K). In this case, we can convert the pressure from 40 kPa to 400 N/m² and use the ideal gas law (PV = nRT) to find the number of moles (n) of gas. Then, we can use Avogadro's number (6.022 * 10^23 mol^-1) to find the total number of gas molecules. Using this information, we can calculate the average kinetic energy of each molecule to be approximately 1.38 * 10^-19 J. This shows that even though the concentration of the gas is high, the individual molecule still has a relatively low kinetic energy, which is important to consider in terms of gas behavior and properties.
