Interstellar space, far from any stars, is filled with hydrogen atoms (1.0 atom/cm³) at 3.0 K. The pressure in the interstellar space is

Question

Quizplus · Accepted Answer

The pressure in an ideal gas is given by the equation P = nkT, where n is the number density of the gas, k is the Boltzmann constant, and T is the temperature. In this case, the number density is 1.0 atom/cm³, the Boltzmann constant is 1.38 $\times$ 10^-23 J/K, and the temperature is 3.0 K. Plugging these values into the equation, we get P = (1.0 atom/cm³) $\times$ (1.38 $\times$ 10^-23 J/K) $\times$ (3.0 K) = 4.1 $\times$ 10^-23 N/m².
