Interstellar space, far from any stars, is filled with a very low density of hydrogen atoms (H, not H2). The number density is about 1 atom/cm3 and the temperature is about 3 K. a. Estimate the pressure in interstellar space. Give your answer in Pa and in atm. b. What is the rms speed of the atoms? c. What is the edge length L of an L × L × L cube of gas with 1.0 J of thermal energy?
π Solution Approach
Given: 3 K, . a, 1.0 J
