To analyze the situation:
1. The ice cubes are at 0 °C, while the water is at 50 °C.
2. Heat energy will flow from the warmer substance (the water) to the colder substance (the ice cubes) until thermal equilibrium is reached.
3. When heat is transferred, the ice will absorb energy and melt, while the water will lose energy.
Since the ice is initially at 0 °C, it will take some of the thermal energy from the water to first melt and then possibly warm up to a certain temperature, but because the water starts at a much higher temperature, it will only cool down.
The final equilibrium temperature will depend on the specific heat capacities and the heat fusion of ice, but it will be less than 50 °C, potentially around 25 °C if enough ice is used, but we can't definitively say without more details.
Given that:
- Heat flows from water to ice.
- The temperature of the water will decrease, and the temperature of the ice will increase (until the ice has melted into water and possibly warms up further).
The most accurate option based on the principles of thermal equilibrium and the temperature effects described would be:
**c. Thermal energy will flow from the water to the ice cubes until they reach equilibrium at 25 °C.**
