Answer: Energy cannot be <u>created</u> or <u>destroyed</u> just <u>changes</u> in form.
Explanation:
This is the principle of the first Law of Thermodynamics, which relates the work and the transferred energy exchanged in a system through the internal energy, which is neither created nor destroyed, it is only transformed.
In other words: The total energy of a system is always conserved.
Energy =mass*SHC*temp rise
670*0.96*218
=140217.6J
=140.2176KJ
