A persons or animals nature, especially as it permanently affects their behavior
        
             
        
        
        
Answer:
it is the judicious use of energy to prevent wastage
 
        
             
        
        
        
Answer:
yes
Explanation:
using law of HC(heat capacity), which is
- heat loss=heat gain
- energy H=MCQ
Where M is mass of substance,C is specific heat capacity, and Q is temperature change
In case of two substance
- the H = Mc*Cc*Q+Mw*Cw*Q(provided the initial and final temperature are given)
 
        
             
        
        
        
A. Getting a full set of valence electrons
Explanation:
The best description of the end result of chemical bonding for most atoms is the getting of a full set of valence electrons. 
Atoms reacts with one another in order to complete valence electronic shell. 
- The valence electron shell is the outermost energy level of an atom. 
- It is from this energy level that electrons are lost or gained to form bonds. 
- All atoms wants to be like the noble gases whose valence electronic shell is completely filled up
- This is the crux of chemical bonding 
- The attraction that is produced from the interaction leads to bond formation
