Question

Mrs. Aldaco adds a room-temperature

she just removed from the freezer to a beaker of boiling water.
Before
copper (Cu) cube and an aluminum (Al) cube that
After
She left the cubes in the water for three hours. Which of the following describes a heat
flow that took place during those three hours?
from the copper cube to the boiling water
from the aluminum cube to the copper cube
from the boiling water to the aluminum cube
from the aluminum cube to the beaker

Answer 1

from the boiling water to the aluminum cube

Step-by-step explanation:

: )

Answer 2

Step-by-step explanation:

During the three hours, a heat flow took place from the boiling water to both the copper and aluminum cubes, as the water was at a higher temperature than the room-temperature cubes. However, the direction of heat flow between the two cubes depends on their respective thermal conductivities, specific heat capacities, and initial temperatures, which are not provided in the question. Therefore, the correct answer cannot be determined based on the information given.
