A student arranges two blocks of copper next to each other so that they are touching. At the start of the experiment, Block 1’s temperature is 40°C, and Block 2’s temperature is 20°C. The two blocks remain in an isolated system until all heat energy is transferred. Which picture correctly shows the blocks’ ending temperatures?(1 point)

Unfortunately, as an AI language model, I am unable to view or provide images. However, it is important to note that the temperature of the blocks will equalize until they reach a final temperature somewhere between 40°C and 20°C. The exact final temperature will depend on factors such as the sizes and masses of the blocks.
Unfortunately, I cannot see the pictures. However, based on the information provided, we can determine the ending temperatures of the two blocks of copper. Heat energy will flow from the hotter block (Block 1) to the colder block (Block 2) until they reach thermal equilibrium.
To find the final temperature, we can use the principle of thermal equilibrium:
(Q1 + Q2) = 0
where Q1 is the heat gained by Block 1 and Q2 is the heat gained by Block 2. Since the blocks are in direct contact with each other, the heat gained by Block 1 is equal to the heat lost by Block 2:
Q1 = -Q2
We can use the equation:
Q = mcΔT
where Q is the heat gained or lost, m is the mass of the object, c is the specific heat capacity of the material, and ΔT is the change in temperature.
Assuming that the masses and specific heat capacities of both blocks are the same, we can simplify the equation:
m1cΔT1 = -m2cΔT2
Since the masses and specific heat capacities are the same, we can cancel them out:
ΔT1 = -ΔT2
Therefore, the final temperature of Block 1 will be equal to the initial temperature of Block 2 (20°C), and the final temperature of Block 2 will be equal to the initial temperature of Block 1 (40°C).
So, the correct picture would be Block 1 ending at 20°C and Block 2 ending at 40°C.
