A student collects a 250 cmsample of neon gas at 294 K. If the pressure of the gas remains constant, at what temperature will the volume of the gas be 525^3 cm?

i don t now

the answer is option a.

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.
