The Sun can explode in a supernova. Around the time that sun (massive star) burning finishes, the inert core of Iron in very massive stars will collapse and the star will explode as a supernova.
When the sun explode, their inert iron cores often collapse into an extremely dense neutron star.
In a massive star, hydrogen fusion in the core is accompanied by other different fusion reactions involving heavier elements.
When the core of a massive star dies during a supernova, The supergiant will explodes as a supernova.

<span>Animal Y is an invertebrate, and animal Z is a vertebrate.
An x-ray can produce images of structures found inside the body. Based on the image, you can see that Animal Z has a backbone, which is a series of small bones called vertebrae that extend from the head. Animal Y does not have that structure.
Vertebrates are organisms that have a backbone and invertebrates are organisms that lack one. </span>
Answer:
Explanation:
Given
n=5
0.3 fraction recrystallize after 100 min
According to Avrami equation
where y=fraction Transformed
k=constant
t=time
Taking log both sides
At this Point we want to compute 
taking log both sides
Rate of Re crystallization at this temperature
