when water is at 0°C, can it be a solid, a liquid, or both a solid and a liquid?
At zero degree Celsius water starts freezes to ice. But the melting point of water is zero degree itself. Hence, if the ice is kept at room temperature it starts to melt. Thus, there will be both solid and liquid.
What is freezing point ?The freezing point of a substance is the temperature at which its liquid state converts to solid state. The freezing point of a substance depends on the bond type, molar mass, temperature and pressure.
The freezing point of water is 0°C. Hence, from 0°C, liquid water starts to freeze to form ice. If the ice at this temperature kept at room temperature, it starts to melt.
If the water is kept at the 0°C itself there will be ice only. If the temperature changes in surroundings, the ice starts to melt. Hence, there will be both ice and liquid water till the ice completely melt.
