What happens to interstellar gas as it passes through a spiral density wave?
what happens to interstellear gas as it passes through a spiral density wave
Why are interstellar absorption lines so much thinner than stellar absorption lines?
Most interstellar gas is at a lower temperature than that of stellar atmospheres and the density of interstellar gas is less than that of stellar atmospheres.
What do forbidden lines reveal about interstellar space?
The density or pressure of this gas is much lower than can be produced in a laboratory.
What is interstellar matter made of?
The interstellar medium is an extremely sparse (tenuous) mix of gas and dust, some of the gas being ionized, some atomic, and some molecular. By composition the gas is largely hydrogen, with smaller amounts of helium and very small amounts of heavier elements. There are also cosmic rays which are protons and nuclei which have been accelerated to near-relativistic speeds. In cooler, high-density areas, the interstellar medium can become as dense as one ten-billionth that of air.
What is least dense metal?
Lithium is the metal with the least density. It is in the 1st period. The density of it is 0.53gm-3.

What is interstellar gas cloud?
An interstellar cloud made of gas, dust, and plasma in a galaxy.
What is a diffuse mass of interstellar dust and gas?
An interstellar cloud.
Of the 3 physical statesliquid solid gas of a compound which has the lowest density?
well becase of its physical properties water is less dense
Stars form from?
Interstellar gas and dust.
What is an interstellar cloud of gas or dust?
A nebula is what it is. :)
What was the earth created from?
Interstellar gas and debris.
What is a large cold cloud of gas and dust in interstellar space?
These are generically referred to as, not surprisingly; 'interstellar clouds'
