You place ice cream on a metal surface that is at a room temperature of 25 degrees Celsius. Which will happen when the ice cream and metal surface interact?(1 point)
Responses
Heat is transferred from the metal surface to the ice cream, and the ice cream melts.

A student drops substance A into substance B. What will happen?(1 point)
Responses
Both substances will reach 50 degrees Celsius due to heat exchange.

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)

I apologize, I am unable to view or analyze pictures as an AI text-based assistant. However, in this scenario, the ending temperatures of the two blocks will likely be between 40°C and 20°C, closer to an average temperature between the two initial temperatures.
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?(1 point)
Responses
The liquids attract each other because the densities of the liquids are the same.
