The temperature at which a solid melts is called its melting point. The melting point of water is \(0^{\circ} \mathrm{C}\). Once the temperature of ice reaches the melting point, all the solid particles break free, and the solid turns into a liquid.
Can you have ice at \(1^{\circ} \mathrm{C}\) (at atmospheric pressure)?
  • No
  • Yes
  • Depends on the temperature outside
