Because the latent heat of fusion and latent heat of vaporization are very high
No, the boiling point and the melting point are not always the same. The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid.
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
It stops rising because, when the heat of the ice rises, the temperature just stops
When water is heated, the temperature increases until the boiling point. During the transition from liquid water to gaseous water (steam), the temperature does not change, and the the temperature rises again.
boiling point
When water is heated steadily, its temperature will stop rising when it reaches its boiling point and starts to convert into vapor. This process is known as boiling and occurs at a specific temperature depending on air pressure.
Ice will melt if the surrounding temperature rising above freezing point.
Rising the temperature to 801 0C sodium chloride is melted.
Condensation
The temperature of a substance can remain the same during absorbing thermal energy if the substance is undergoing a phase change, such as melting or boiling. During a phase change, the absorbed thermal energy goes into breaking intermolecular bonds rather than increasing the temperature. Once the phase change is complete, the temperature will resume rising as the substance absorbs more thermal energy.
Simmering is a cooking technique where food is cooked gently in liquid at a temperature just below boiling. It differs from boiling in that boiling involves cooking food in liquid at a higher temperature where bubbles break the surface, while simmering involves cooking at a lower temperature with smaller bubbles gently rising to the surface.
Water is boiling when it reaches a temperature of 212 degrees Fahrenheit (100 degrees Celsius) at sea level. You can tell water is boiling by seeing bubbles forming and rising to the surface.
