Matching
Match the four components of the interstellar medium (ISM) with theirrespective description. You may use the choices more than once.
Premises:
A chaotic shape that is usually twisted, flattened, and tangled
Highly ionized state
The hot space of ISMs with temperatures of a few thousand K and a density of only 0.1 atom per cubic centimeter found between the cool H I clouds
Clouds of gas and dust with densities ranging from 100s-1000s particles per cubic centimeter, found deep inside the ISM, where it is protected from UV photons
ISM clouds of cool gas of only about 100 K and dust with densities ranging up to 100 atoms per cubic centimeter and observed only at infrared and radio wavelengths
The coolest temperature
The part of the ISM that can only be detected with X-ray telescopes have has temperatures of 10 6 K or higher
Responses:
H I cloud
Molecular clouds
Intercloud medium
