Answer 1

The best explanation for what will occur over time when you place a piece of iron at 75 °C into a large container of water at 25 °C is:

D. Some heat from the iron will move to the water causing both to change temperatures.

This is because heat will flow from the hotter object (the iron) to the cooler one (the water) until thermal equilibrium is reached, meaning both will eventually reach the same temperature.
