Energy is required in the melting process because high is needed to melt something

∙ 6y agoBecause water requires heat to vaporise it. This is called latent heat. It is absorbed during change from liquid to vapor, and released on condensation of vapor to liquid. there is a similar latent heat transfer during freezing and melting of water (and other substances)

∙ 14y agoThat's because of all the bonds that hold the substance your heating or boiling together. When you heat or boil something your breaking these bonds which requires energy.

∙ 14y agobecause when you melt stuff you have to heat it to high temperatures so you need to use a furnace which requires energy.

Why do electrovalent compounds have high melting and boiling points?
Electrovalent compounds have high melting and boiling points as they are held by very strong electrostatic force of attraction making the compound stable and therefore they require a lot of energy to break.
Is evaporation the same as boiling?
they are both vaporization process, but evaporation occur on the surface and boiling occur by forming completed bubbles from the bottom.
Does melting require an input of energy?
Yes.
Why does the temperature of a substance remain constant during its melting point and boiling point?
Melting and boiling are changes of state. Melting changes state from solid to liquid, and boiling changes state from liquid to vapor. Thus, these are physical, not chemical changes. All of the heat energy that goes into changing solid to liquid or liquid to vapor (or any change of state for that matter), is used only to change the state and therefore the temperature of the system does not change.
What do you need to melt a solid in energy flow terms?
Melting is an exothermic process; we need heat for melting.
Why is energy required for the melting or boiling process?
Energy is required in the melting process because high is needed to melt something
What requires more energy melting or boiling?
Melting requires energy input or absorption because liquid water has more energy than solid water.
Why do electrovalent compounds have high melting and boiling points?
Electrovalent compounds have high melting and boiling points as they are held by very strong electrostatic force of attraction making the compound stable and therefore they require a lot of energy to break.
Are boiling and melting the same?
No boiling is heating and energy is added and melting the solid turns into a liquid.
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.
Is evaporation the same as boiling?
they are both vaporization process, but evaporation occur on the surface and boiling occur by forming completed bubbles from the bottom.
Does melting require an input of energy?
Yes.
Why do impurities lower the boiling point of a pure substance?
The presence of the impurities will cause the boiling points to rise (also the melting points to fall). When you add the impurities, the substance doesn't remain pure affecting the boiling point to increase because now, more energy is required to boil the liquid with impurities. The melting points fall because impure substances require less energy to separate the particles.
What are three change of state in which energy is absorbed?
Energy is absorbed during melting, boiling and sublimation.
What changes of state require energy?
Sublimation, melting, and vaporization are three changes of state which require energy.
What are changes of state that require energy?
Melting & evaporating.
What processes do particles of matter absorb energy freezing and boili condensation and melting melting and vaporization or sublimation?
Particles absorb energy when boiling (vapourising), melting and subliming. Particles release energy when freezing and condensing.
