If I have 21 liters of gas held at a pressure of 78 atm and a temperature of 900.0 K, what will be the volume of the gas if I decrease the pressure to 45 atm
and decrease the temperature to 750.0 K?

mention the spill to the teacher clean the area and throw the broken pieces away

explanation:

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.
