Why is energy require for melting or boiling process?
Energy is required in the melting process because high is needed to melt something
Why does temperature does not rise during the process of boiling and melting though heat energy is constantly supplied?
you must have observed during the experiment of melting that the temperature of the system does not change after the melting point is reached till all the ice melts this happens even though we continue to heat the breaker that is we continue to supply heat
Where is the heat energy going when a substance is boiling?
The energy is used to maintain the temperature at the boiling point.
Where all the heat energy is going when a substance is boiling?
The energy is used to maintain the temperature at the boiling point.
Why are the freezing melting and boiling points lower on high altitude?
Heat is only energy. In areas of low pressure, such as high altitudes, "heat" particles, which are charged electrons, escape more quickly. As more "heat" (electrons) escapes more quickly, things freeze more quickly. As far as I know melting and boiling points are higher, not lower in high altitudes.
What requires more energy melting or boiling?
Melting requires energy input or absorption because liquid water has more energy than solid water.
How is melting and boiling alike?
They are both phase changes, this means that until the melting or boiling are complete the temperature of the system remains at the melting or boiling point, despite the continued input of heat energy.
Why is heat energy needed to melt a solid. What is this heat energy called?
the energy that goes into changing a substance from a solid to a liquid (melting) is called the latent heat of fusion.
Water changes phases when heat is added or subtracted?
Boiling and melting are endothermic. Freezing is exothermic.
Which phase change occurs when a substance absourbs thermal energy?
melting and vaporization (evaporation and boiling)

Why do metallically bonded compounds have high melting and boiling points?
Metallically bonded compounds have high melting and boiling points due to the strength of their bonds. Metallic bonds are very strong and therefore take a lot of energy to break, which could be heat. This is why lots of heat energy is needed to break down each individual metallic bond
Can heat be added to a substance without causing temperature of the substance to rise?
Yes, if the heat goes into a phase change.For example . . .Heat added to ice at 0° C changes the ice to water at the same temperature.Heat added to water at 100° C changes the water to steam at the same temperature.
Why the temperature does not rise during the process of melting and boiling though the heat energy is constantly supplied?
The energy must be applied to the phase change before it can heat the substance
Where is the heat energy going when a substance is boiling?
The energy is used to maintain the temperature at the boiling point.
Why temperature remains constant during the process of melting or boiling?
This is because of latent heat. When a substance is being melted, heat is supplied to the solid until its melting point is reached. When the solid reaches that temperature, any additional heat energy is used - not to raise its temperature - but to cause the phase to change from solid to liquid. The amount of energy required (per unit mass) is the latent heat of melting (or freezing, when the process is reversed) for that substance. When the phase change is complete, any further heat energy supplied will, once again, go towards raising the temperature.The same thing happens at the boiling point except that this time it is the latent heat of evaporation/condensation.
