Answer :
Final answer:
The final temperature when a 32.4 g iron rod at 22.7 °C is submerged in water at 64.0 °C, leading to thermal equilibrium, is 59.1 °C.
Explanation:
The given problem involves the concept of heat transfer until thermal equilibrium is reached. We are given that a 32.4 g iron rod at 22.7 °C is introduced into water at 64.0 °C and the system reaches a final temperature of 59.1 °C.
No calculation is needed here since the final temperature is provided in the question as 59.1 °C, which is the temperature at which the iron rod and the water reach thermal equilibrium. This means that heat is transferred from the hotter substance (water) to the cooler substance (iron rod) until both substances reach the same temperature. Based on this description, the correct answer to the student's question is b) 59.1 °C.
