Heat is transferred directly from a heat reservoir at 200 c to another heat reservoir at 5c. if the amount of heat transferred is 100kj, what is the total entropy change as a result of this process? draw a schematic to represent the heat exchange

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.
