What is the relationship between dipole moment and boiling point?

The relationship between dipole moment and boiling point is that dipole moments increase with polarity of the H-X bond (the greater the difference of the elctronegativity between H and halogen atoms, the stronger the dipole – dipole moments).

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
