Question

What istheresistanceofagastotheflowofradiation? hydrostatic pressure opacity degeneracy conduction gravitational pressure Stars with masses equal to or less than 1.1 solar masses use the_____ to convert H into He for their energy source. The proton-proton chain for fusing hydrogen into helium is a much more complicated process than the CNO Cycle for fusing hydrogen into helium. True False Very massive stars live relatively short lives True False When a protostar becomes hot enough to fuse hydrogen into helium, it becomes a Main sequence star Red giant White dwarf Planetary nebula Variable star

Explanation / Answer

9)The resistance of gas to thermal radiation is called as opacity. Since opacity is the ability of a body to not allow something to pass through.

10) the proton-proton chain reaction

11) False . The CNO cycle is more complicated as it involves a larger setup of conversion to higher elements

12) True . It is because very massive stars have very high rate of conversion of hydrogen to helium ,hence the energy source gets over faster and hence the relatively shorter life

13) Main Sequence star
