Asample of neon has a volume of 5.00 l, and initial temperature of 425 k, and an initial pressure of 1.23 atm. if the final temperature is 288 k, and the final volume is 0.555 l, what is the final pressure?
5.04 atm
7.51 atm
1.82 atm
9.08 atm

7.51

Explanation:

general gas law

the product of pressure and volume is divided by absolute temperature

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.
