Question

The melting point of pure ice and freezing point of pure water is both______

Answer 1

1. Melting point: The temperature at which a solid changes to a liquid state by absorbing heat at a constant temperature is called the melting point.
2. For example, the melting point of pure ice is $0^{°}C$
3. Freezing point: The temperature at which a solid changes into liquid by releasing heat at a constant temperature is called the freezing point.
4. For example, the freezing point of pure water is $0^{°}C$

Hence the right answer is: The melting point of pure ice and the freezing point of pure water are both $0^{°}C$.
