hey, what do you need . just post the question and i may be able to you : )

not only is it colder, it also becomes darker, less salty, and more dense.

the correct answer to this question is #5

option d : from a warmer substance to a cooler substance

according to second law of thermodynamic, heat flows from higher to lower temperature region. heat is the transfer of energy from an object at higher temperature to an object at a lower temperature. so energy flows from warmer to colder objects.
