A cook uses a ladle to stir a pot of warm soup. The soup is at a temperature of 85°C, and the ladle is at 25°C. Which sentence correctly describes heat flow in this system?
A. Heat will flow from the ladle to the soup until they reach the same temperature.
B. Heat will flow from the soup to the ladle until they reach the same temperature.
C. Heat will flow from the soup to the ladle because heat always flows from liquids to solids.
D. Heat will flow from the ladle to the soup because heat always flows from solids to liquids.
Answer (2)
Heat will flow from the soup at 85°C to the ladle at 25°C until they equilibrate at the same temperature. This process is governed by the second law of thermodynamics, which dictates the direction of heat transfer. The correct answer is that heat flows from the soup to the ladle. ;
Heat will flow from the soup at 85°C to the ladle at 25°C until they reach the same temperature, as heat transfers from hot to cold objects. Thus, the correct answer is B. Heat will flow from the soup to the ladle until they reach the same temperature.
