Which statement describes the phase change that occurs when dry ice is placed in an open container at room temperature? A. Dry ice undergoes deposition, an endothermic change, at room temperature.
B. Dry ice undergoes sublimation, an endothermic change, at room temperature.
C. Dry ice undergoes sublimation, an exothermic change, at room temperature.

well, their are quite a few differences !

explanation:

first difference is a main sequence star is made of carbon, while a neutron star is made of neutrons. another difference is a main sequence star still has hydrogen to burn, while a neutron star is a remnant of a supernova.

a main sequence star is what’s left over from a low-mass star death, while a neutron star is what’s left from the death of a high-mass star. main sequence star and a neutron star are considered the same thing, except a main sequence star spins.
