In the space between two stars, the temperature of a gas cloud is 12 K; and the density of the gas is 1.2 × 10^-⁸atom/m³.What is the absolute pressure of the gas?

Question

Quizplus · Accepted Answer

The absolute pressure of an ideal gas can be calculated using the formula P = n*k*T, where n is the number density, k is the Boltzmann constant (1.38 × 10^-23 J/K), and T is the temperature in Kelvin. Substituting the given values, P = (1.2 × 10^-8 atoms/m^3) * (1.38 × 10^-23 J/K) * (12 K) = 2.0 × 10^-30 Pa.
