Identify the concept of thermal energy flow, which is related to the amount of heat transferred between substances. The flow of thermal energy depends on the mass of the substance and its temperature.
Recognize that all containers have water at the same temperature (50°C), so the temperature difference is not a factor in determining the greatest flow of thermal energy.
Understand that the flow of thermal energy in the form of heat is proportional to the mass of the substance, given the same temperature. More mass means more thermal energy can be transferred.
Compare the masses of water in each container: 40 g, 120 g, and 30 g. The container with the largest mass will have the greatest flow of thermal energy.
Conclude that the container with 120 g of water at 50°C will have the greatest flow of thermal energy in the form of heat, as it has the largest mass among the options provided.
