Part 1 (1 point)

Why can't heat flow from a cold object to a warm object? Choose the BEST answer.

Choose one:

ⒸFlow of heat from cold to hot decreases the entropy of the universe.

O Flow of heat from cold to hot requires the entropy for one of the objects to go down.

O Flow of heat from cold to hot violates the principle of conservation of entropy.

O Flow of heat from cold to hot violates the principle of conservation of energy.

Part 2 (3 points)

Suppose that you have Object "A" at 291.1 K and Object "B" at 608.3 K. Each of these Objects is a closed system and together they are

isolated from their surroundings. The Objects come in contact, and 2375 J of energy passes from Object "B" to Object "A",

without changing the temperature of either Object.

What is the magnitude of the change in entropy for Object "A"? Do not include + or - signs.

What is the magnitude of the change in entropy for Object "B"? Do not include + or - signs.

What is the total change in entropy of the universe? For this part of the problem, you need to use the correct signs for the entropy

changes of each object. If your answer is negative, include a negative sign.
