Answer 1

To determine the direction of heat flow between two solid blocks at different temperatures, we need to apply the principle that heat flows from areas of higher temperature to areas of lower temperature.

If Block A is at a higher temperature than Block B, heat will flow from Block A to Block B. Conversely, if Block B is at a higher temperature than Block A, heat will flow from Block B to Block A.

However, without the specific temperature values or diagrams that illustrate the temperature difference between Block A and Block B, I can't definitively indicate which diagram shows the correct direction of heat flow.

If you provide me with the temperature values or more context about the blocks, I could help you identify the correct option.

Question
Two friends bought phones that cost different amounts but had identical batteries. After using the phones for a while, both friends had to turn them off to let the batteries cool. This table shows how the temperature of each battery changed over 5 minutes.

Answer 3

To answer the question regarding the thermal energy transfer between the two batteries, we generally need to consider the direction of heat flow based on the temperature of each battery.

If the temperature of one battery is higher than the other, thermal energy will flow from the battery with the higher temperature to the one with the lower temperature.

Since you mentioned placing responses in the correct input areas but did not specify what those response areas are, let’s construct a general response based on the common context of the scenario provided:

1. Response area (for the hotter battery): This would be the battery that had the higher temperature after use.
2. Response area (for the cooler battery): This would be the battery that had the lower temperature after use.

In the sentence "During this time, thermal energy was transferred from [hotter battery] to [cooler battery]."

If you provide me with the specific temperatures of the two batteries or more context, I can help you fill in the blanks more accurately.
