Answer to Question 1

Neutral hydrogen dominates the composition of interstellar matter. The hydrogen exists as single atoms of hydrogen at a temperature of about 100 K. Typical densities are 1 atom/cubic centimeter or higher in clouds. Clouds of neutral hydrogen move around the Galaxy much like stars do. Neutral hydrogen emits a characteristic radio radiation at a wavelength of 21 cm. Because this wavelength is so long, it can travel unimpeded by dust clouds through the entire Galaxy. Observations of 21 cm radiation are useful in studying the velocities, densities, and distribution of neutral hydrogen and in mapping the entire Galaxy.

Answer to Question 2

TRUE
