Inside a laboratory at $20^{\circ}\text{C}$, there is a piece of ice that is melting at $0^{\circ}\text{C}$ together with a beaker of boiling water. What is happening to the temperature of the melting ice, and what is happening to the temperature of the boiling water?
- Amelting ice: constant; boiling water: constant
- Bmelting ice: constant; boiling water: increasing
- Cmelting ice: increasing; boiling water: constant
- Dmelting ice: increasing; boiling water: increasing
