Describe thermodynamic concepts and their applications. Extend the first law of thermodynamics to various daily life activities. Identify the maximum efficiency of a heat engine. Explain the role of latent heat while phases are changing.

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

a. hope i'm right

explanation:

12 is it do you think so

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.
