Answer:
The particles should move faster and have more space between them.
Explanation:
As the molecules heat, they should start to vibrate with the energy. When they vibrate, the space between them increases.
To develop this problem it is necessary to apply the concepts related to the proportion of a neutron star referring to the sun and density as a function of mass and volume.
Mathematically it can be expressed as

Where
m = Mass (Neutron at this case)
V = Volume
The mass of the neutron star is 1.4times to that of the mass of the sun
The volume of a sphere is determined by the equation
Replacing at the equation we have that



Therefore the density of a neutron star is 
Answer:
by measuring calender we can find
