The melting and freezing temperature of water are the same: 0o C; thus, both water and ice can exist at this temperature. Lets say a block of ice is starting at a temperature below the melting point. As the temperature of the ice rises, the heat energy being transfered into it goes to raising its temperature, but when the temperature reaches the melting point, the heat energy introduced does not go into raising the temperature but instead into breaking the bonds holding it as a solid. The ice-water mixture will remain at 0o until all of the ice has fully melted. Only after all of the ice has melted does the heat energy go into heating the water.

What do melting and evaporation have in common?

melting and evaporating are both a change in matter. also during evaporation and melting there is no change in temperature. melting and evaporating are both a change in matter. also during evaporation and melting there is no change in temperature.


How is melting similar to evaporation?

Melting and evaporation are both phase changes that involve a substance transitioning from a solid to a liquid state. In both processes, energy is absorbed to break intermolecular bonds and increase the kinetic energy of the molecules. The main difference is that melting occurs at a specific temperature for a given substance, while evaporation can occur at any temperature as long as enough heat energy is applied.


What happens to the water in the beaker during melting?

During melting, the water in the beaker absorbs heat and undergoes a phase change from solid (ice) to liquid. As it melts, the temperature remains constant until all the ice has transformed into water.


Melting sugar cube is what change because the substance still is sugar?

Melting a sugar cube is a physical change because the substance remains sugar, just in a different form (solid to liquid). The chemical composition of sugar does not change during the melting process.


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.

Did the temperature fluctuate while the is melting?

No. The temperature does not change during the melting process. All of the heat energy is used to break the bonds of the solid to form a liquid, i.e. the energy is used in the phase change, and thus is not used to raise the temperature.


A change of occurs during both freezing and melting?

A change in temperature occurs during both freezing and melting. Freezing and melting are physical changes since the chemical contents of the matter do not change.


Is it true that a star doesnt change its size or temperature during its life?

No, that's not true.

Does a substances temperature change when it is changing state?

No. During a phase change, a substance will remain at a constant temperature until the change is complete. In the case of melting ice, the heat initially goes into separating water molecules from the ice lattice, which is melting. During that time, the heat goes into continued melting of the ice and the temperature remains constant. Once all of the ice is melted, adding additional heat will increase the temperature of the now liquid water.


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.


When does a substance donot change its temperature even if it is heated?

During a phase change, a substance will remain at a constant temperature while it is being heated. In the case of melting ice, the heat initially goes into separating water molecules from the ice lattice, which is melting. During that time, the heat goes into continued melting of the ice and the temperature remains constant. Once all of the ice is melted, adding additional heat will increase the temperature of the now liquid water.


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)


A change of what occurs during both freezing and melting?

A change of solid occurs during both freezing and melting.


When can you withdraw heat from something without lowering it's temperature?

You can withdraw heat from something without lowering its temperature during a phase change, such as during melting or boiling. As the substance absorbs energy to undergo a change in state, its temperature remains constant until the phase change is complete.


During a temperature change what is happening to the substance?

A change of phase: melting, evaporation, liquefaction or chemical changes as thermal dehydration, thermal decomposition, oxydation, etc.
