In a laboratory, there is a lump of ice that is melting at $0^\circ\text{C}$ and a beaker containing boiling water. The laboratory temperature is $20^\circ\text{C}$. What happens to the temperature of the melting ice, and what happens to the temperature of the boiling water?
- Atemperature of melting ice: constant; temperature of boiling water: constant
- Btemperature of melting ice: constant; temperature of boiling water: increasing
- Ctemperature of melting ice: increasing; temperature of boiling water: constant
- Dtemperature of melting ice: increasing; temperature of boiling water: increasing
