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
As a text-based AI, I am unable to directly provide pictures. However, I can describe what the picture should show based on the information provided.
The correct picture should show Block 1 and Block 2 with equal temperatures. In this case, both blocks would end up at a temperature between 40°C and 20°C, depending on the amount of heat transferred between them. The specific temperature at which they would eventually stabilize would require additional information, such as their masses and specific heat capacities.
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
Cold liquids rise and hot liquids sink making the liquids mix.
Cold liquids rise and hot liquids sink making the liquids mix.
The molecules of the two liquids form chemical bonds to spread energy.
The molecules of the two liquids form chemical bonds to spread energy.
Heat always moves from areas of higher temperature to areas of lower temperature.
Heat always moves from areas of higher temperature to areas of lower temperature.
The liquids attract each other because the densities of the liquids are the same.
Heat always moves from areas of higher temperature to areas of lower temperature.
To determine what will happen when the ice cream and metal surface interact, we need to understand the concept of heat transfer. Heat always flows from a higher temperature to a lower temperature.
In this scenario, the room temperature is 25 degrees Celsius, which is higher than the temperature of the ice cream. Therefore, heat will transfer from the metal surface to the ice cream.
Hence, the correct response is: Heat is transferred from the metal surface to the ice cream, and the ice cream melts.
