The diagram is being used to illustrate the second law of thermodynamics, where qh represents a hot object and qc represents a cold object.

a black box on the left labeled q subscript h baseline and a touching white box on the right labeled q subscript c baseline.

which will best complete the diagram to illustrate the law?

adding in the boxes an arrow that points from qh to qc
adding in the boxes an arrow that points from qc to qh
adding in the boxes an arrow that points in both directions between qh and qc
adding in each box an arrow that points upward from qh and from qc

the correct answer is a. adding in the boxes an arrow that points from qh to qc

Adding in the boxes an arrow that points from to .

Explanation:

According to the Second Law of Thermodynamics, the heat transfer occur from a higher temperature body to a lower temperature body.

So, applying the Second Law of Thermodynamics, the correct answer is the first one: Adding in the boxes an arrow that points from to ; because this direction is pointing the right one, it doesn't violate the second law of the thermodynamics, the heat is gonna go from to , and the arrow indicates that.

Remember that the problem states that is a cold object and is a hot object.

! 55 !  

write a paragraph or story to explain the transformation between potential and kinetic energy as shown in your picture or model.  

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))

where is the photo and the answer choices?
