a recycling plant manager needs to melt 15.0g of copper to sell to a wire manufacturer. The copper is at 15C and it's melting point is 1083c. The copper has a specific heat of .385 J/(gC) how much heat is required to raise the temperature of the copper to its melting point

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

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.
