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

Answer 1

It seems like your question was cut off before you could specify the picture or the concept you wanted to illustrate. However, I can explain the concept of heat transfer between the two copper blocks.

In this scenario, Block 1, initially at 40°C, will transfer heat to Block 2, which is at 20°C. Heat will flow from the hotter block (Block 1) to the cooler block (Block 2) until thermal equilibrium is reached, meaning both blocks will eventually have the same temperature.

Here’s a step-by-step outline of what would happen:

1. Initial Temperatures:

   • Block 1: 40°C (hotter)
   • Block 2: 20°C (cooler)

2. Heat Transfer:

   • Heat energy will flow from Block 1 to Block 2. This process will continue until both blocks reach a common equilibrium temperature.

3. Final Temperature:

   • The final equilibrium temperature will be somewhere between 20°C and 40°C, depending on the specific heat capacities and masses of the two blocks.

If you wanted a visual representation, it would typically show arrows indicating the direction of heat flow from Block 1 to Block 2 and possibly indicate the final temperature.

If you let me know specifically what kind of picture or concept you are referring to, I can provide more tailored information!
