Liquids in equilibrium with solids have a higher enthalpy even though the Gibbs free energy is zero for the transition. Some energy has to be added in order to make the transition but it does not go into speeding up the molecules - rather it goes into breaking the bonds holding the molecules in place in the solid so the temperature does not rise.

What happens when the temperature stays the same in a melting curve?
During melting the temperature remain constant if it was achieved the melting point.
Ice melts at o degree centigrate the temperature remain constant at o degree centegrate until all the ice has melted suggest why the temperature remains constant during melting although heat is abs?
At melting point of a substance the supplied heat is utilized to change the state so temperature remains constant till all the material is converted into liquid, this is known asLatent heat of fusion.
Explain what happens to the temperature of an ice cube as it melts?
Temperature of melting iceis a constant property: it does not change during melting (stays 0oC, this is even one of the the defined value of the Celsius temperature scale)(for any other melting solid the same is valid at each melting point temperature)
Since the melting and freezing temperature are the same does something stay the same temperature when it is melting?
When a substance is melting, it stays at a constant temperature until all of it has melted. During this process, the energy being added is used to break the intermolecular forces holding the solid structure together, rather than raising the temperature. Therefore, the temperature remains constant until the phase change is complete.
Do melting and freezing take place at fixed temperature?
Provided other environmental factors remain constant, yes.
Why temperature becomes constant at melting and boiling point?
At the melting point, the temperature remains constant because the energy being absorbed is utilized to overcome the intermolecular forces holding the solid together, rather than increasing the temperature. Similarly, at the boiling point, the temperature remains constant as the energy is used to break the intermolecular bonds holding the liquid together, allowing the substance to transition into the gas phase.
What happens when the temperature stays the same in a melting curve?
During melting the temperature remain constant if it was achieved the melting point.
What is the constant in a experiment on melting rate of ice?
temperature
What does the flat portion of the temperature time graph in the experiment of melting point indicates?
The flat portion of the temperature-time graph during the melting point experiment indicates that the substance is undergoing a phase change. As heat is being absorbed to break the intermolecular bonds and transform the solid into a liquid, the temperature remains constant until all of the substance has melted.

Why does temperature remain constant when wax solidifies?
Temperature remains constant during the solidification of wax because the heat energy released by the wax as it solidifies is absorbed by its surroundings. This is due to the latent heat of fusion, which is the energy required to change a substance from liquid to solid at its melting point without a change in temperature.
What is the melting point temperature?
The temperature at which the solid melts, which remains constant until all of the substance is melted.
Why does the temperature stay the same during melting?
During melting, the temperature remains constant because the heat energy being absorbed by the substance is being used to break the bonds between the molecules rather than increase the kinetic energy of the molecules. Once all the bonds are broken and the substance changes phase completely, the temperature will start to rise again.

Is energy added during melting changes?
No, the temperature remains constant during melting as energy is used to break intermolecular bonds rather than increase the temperature.

Therefore, the temperature remains constant until the phase change is complete.
What is the shape of the graph at the melting and freezing points of water what does this shape tell you about the temperature?
Well, honey, the graph at the melting and freezing points of water is flat as a pancake. This shape tells you that the temperature remains constant during these phase changes. So, don't expect any temperature changes while water is busy melting or freezing, darling.
