Answer
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?
Answer
When you add cold milk and hot chocolate, they will slowly blend as the cooler liquid mixes with the warmer liquid. Eventually, the heat will be spread out evenly through the entire liquid. Which statement best explains why this happens?
A. Cold liquids rise and hot liquids sink making the liquids mix.
B. The molecules of the two liquids form chemical bonds to spread energy.
C. Heat always moves from areas of higher temperature to areas of lower temperature.
D. The liquids attract each other because the densities of the liquids are the same.

I apologize, but I am unable to display or interpret visual information as I am a text-based AI. However, I can describe the possible outcome based on the given information. After the blocks remain in an isolated system until all heat energy is transferred, both blocks will reach an equilibrium temperature somewhere between 40°C and 20°C. The precise temperature at the equilibrium will depend on various factors such as the size and mass of the blocks.
