what is interstellar gas and clouds?

Stars are formed from interstellar clouds which are created by gas and dust clouds that orbit with the stars in our galaxy.
The gas cloud consists of mostly hydrogen and helium. The dust clouds consist of solid and microscopic particles of silicates, carbon and iron compounds.Interstellar gas is usually -10,000 degrees Fahrenheit. At that temperature atoms and molecules in a gas move too slowly to generate much pressure. Because the atoms have little movement the gas may not have enough pressure to support itself against gravity. As a result the gas can form clusters, gas clouds, that collapse due to a collision with another gas cloud or other occurrence.
Interstellar cloud is the generic name given to an accumulation of gas, plasma and dust in our and other galaxies.
