answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

: )

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

i think   the answer is c hope i'm right
