Why does temperature remains constant during the process of melting or boiling?

This is because the heat supplied to the substance is used up in the overcoming the inter molecular forces and therefore , it does not show up as a rise in the temperature. Temperature stays constant until all the interactions are broken.

What happenes to the temperature of a material when it changes state?
Usually it remains constant. For instance when you boil water and it turns into steam, the temperature of the boiling water remains at 100 Degrees Celsius throughout the process.
Which thermodynamic process takes place at a constant temperature so that the internal energy of a system remains unchanged?
If a thermodynamic process takes place at a constant temperature it is called "isothermal". A word of caution however: the internal energy of a system may not remain the same in an isothermal process if the composition or phase changes; e.g. melting ice can be an isodthermal process but there is certainly a change in internal energy when it happens.
What statement best describe the isothermal process?
The temperature remains constant
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.
What is different between adiabatic system and isothermal system?
An isothremal process is one in which the temperature is constant. heat can be gained or lost in order to maintain a constant tempereature. An adiabatic process is one in which there is no heat exchange between a system and its surroundings. It does not matter whether the temperature of the system is constant or not.
What is the equation for isothermal process?
At the boiling point the energy goes into breaking the intermolecular bonds, but the average kinetic energy stays constant and so does the temperature until all of the bonds are broken and the substance is in the vapor state.
Is Melting point higher than boiling points?
No, boiling points are always higher than melting points. When you turn a solid to a liquid, this process is called melting, and requires a lower temperature than boiling the substance. Take ice water for example. Ice becomes pure water at 0oC. The temperature needed to boil pure water is 100oC, which is a bigger number than zero.
What will happen to the temperature of a pot of boiling water as the water evaporates?
As water evaporates from the boiling pot,its temperature drops.This results from the fact that water molecules during evaporation extract its latent heat of vapourization from the pot, thereby exerting a cooling effect on it and its content.Regulation of body temperature by sweating is based on this principle. When sweat comes out of its pores, usually in suny days, it evaporates and in the process extract its latent heat of vapourization from the body.This causes the body temperature to decrease.In this way it keeps the body temperature fairly constant.
Why is energy required for the melting or boiling process?
Energy is required in the melting process because high is needed to melt something
Is boiling the reverse of freezing?
no it is not melting is the reverse of freezing
Why are the melting point and boiling point of the same matter different?
Boiling point is the temperature at which a substance turns into a gas, while melting point is the temperature at which a substance turns into a liquid state from a solid state. The boiling point is always a higher temperature then the melting point. The melting point has a substance turn into a liquid from solid, and boiling point has a liquid turn into a gas.
What requires more energy melting or boiling?
Melting requires energy input or absorption because liquid water has more energy than solid water.
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.
What do you mean by boiling process?
Boiling process is when a substance or liquid is boiled over a specific temperature. Once the temperature reaches the boiling point, the substance or liquid becomes vapor.
Is melting of ice a physical process?
Yes, changes of state (melting, boiling, freezing, condensing) are physical processes.
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
What happenes to the temperature of a material when it changes state?
Usually it remains constant. For instance when you boil water and it turns into steam, the temperature of the boiling water remains at 100 Degrees Celsius throughout the process.
