Question

the diagram below shows a simplified floor plan for a small house. as the day goes on and the sun begins to set, the rooms on the west side of the house grow warmer than the rooms on the east side, as shown by the temperatures in each room. the doors between the rooms are open. which of the following most likely describes the direction of heat flow through the house and the effect of the heat flow on temperature? diagram of house floor plan with room temperatures: room 1 (27°c top and bottom), room 2 (24°c top), room 3 (22°c bottom) from room 3 to rooms 1 and 2 until all the rooms are about 25°c. from room 2 to rooms 1 and 3 until all the rooms are about 27°c. from room 1 to rooms 2 and 3 until all rooms are about 27°c. from room 1 to rooms 2 and 3 until all rooms are about 25°c.

Explanation:

Heat flows spontaneously from a region of higher temperature to lower temperature. Room 1 is the warmest at 27°C, while Room 2 is 24°C and Room 3 is 22°C. Heat will move from Room 1 to Rooms 2 and 3. The final equilibrium temperature will be an average of the three temperatures: $\frac{27+24+22}{3} = 24.33^\circ\text{C}$, which is approximately 25°C.

Answer:

From Room 1 to Rooms 2 and 3 until all rooms are about 25°C.
