What kind of a gas cloud can collapse and form stars?
A.) A very hot gas cloud that has a huge internal pressure can collapse and form stars.
B.) A gas cloud that has a mass less than 10 solar masses can collapse and form stars.
C.) The gas cloud must have a mass that exceeds the Jeans mass so that gravity overcomes the internal pressure in the cloud.
D.) The gas cloud must have a mass that is smaller than the Jeans mass so that gravity overcomes the internal pressure in the cloud.
E.) A black hole can collapse and form stars.
Ans: C.) The gas cloud must have a mass that exceeds the Jeans mass so that gravity overcomes the internal pressure in the cloud.
