A metal block at a temperature of 80 °C is placed in a large container of water at 30 °C. The system is left for a long time in an insulated room. Which statement correctly describes what happens to the temperatures of the block and the water?
- Heat flows from the block to the water until both reach a temperature between 30 °C and 80 °C.
- Heat flows from the water to the block until both reach 80 °C.
- Heat flows from the block to the water until both reach 30 °C.
- Heat flows both ways equally so their temperatures stay at 80 °C and 30 °C.
