The reasons i have learned in my chem classes is that because the trend on the Periodic Table is that as you go down metallic character increases and as you go right to left on the periodic table metallic character increases.

This trend is also the same with melting and boiling points of all elements.

When metals solidify they form metallic-metallic bond. They do not share electrons or steal electrons, but it creates something called an electron sea where each atom of a metal offers some of its valence electrons to this electron sea so that the electrons move around freely filling all the valence shells of atoms in a block of metal.

Another reason why metals solidify is because their melting points are at a higher temperature then our planet reaches. Its the exact same reason why water turns to ice in winter

unless it is Mercury, the temperature INCREASES with the change of solid into liquid. It does not remain constant, which would mean that the temperature does not change. Mercury is the only exception to this rule, as it condenses into a solid mass in liquid due to a higher mass preventing it from mixing with the liquid.

This is known as a phase transition. Until all of the substance is completely frozen, the temperature remains constant. That is how the process works.

When water is heated the temp reaches a constant value and forms a plateau on the graph what does the plateau indicate?

It indicates that the temperature does not change during the phase change from liquid to gas until the change is complete. During the phase change, the heat energy added to the water goes into breaking hydrogen bonds between water molecules, so it does not cause an increase in temperature during that time.


What is the difference between latent heat of fusion and latent heat of vapourization?

the heat which is absorbed by a substance for changing solid into liquid state by keeping temperature constant is called latent heat of fusion while the heat which is evolved during phase change of liquid to vapour state at constant temperature is called latent heat of vapourization


Boiling liquid maintains a constant temperature?

The boiling point temperature remains constant because liquids evaporate at this point. If the temperature drops the liquid will no longer boil. At a higher temperature the vapor becomes hotter, not the liquid.


Explain why the temperature of Wax remains constant during solidification?

it's because it releases the latent heat of fusion. Latent heat means energy is given out when a substance changes from liquid to solid without a change in temperature. and the transfer of energy doesnt change the KE of the particles, so the temperature remains unchanged. lanten heat gives rise to the change in PE of the particles during the change of state only

What happen to the temperature when ice is heated?

During a phase change (from solid to liquid, as in melting and also from liquid to gas as in boiling) the temperature remains constant, as all of the energy is going to affecting the change, rather than raising the temperature. Once it has changed from solid to liquid, the liquid can then raise in temperature.


What is the amount of heat to change liquid into solid at constant temperature?

To change a liquid into solid at constant temperature, an amount of heat is released equal to the latent heat of that liquid. For water it is about 80 calories per gram.


Why does the temperature of a substance remain constant during it's melting point on boiling point?

Because of phase transition ie from solid to liquid during melting and from liquid to vapour during boiling. So just to change over from one phase to the other heat is totally utilized and hence no chance to have a rise in temperature. So temperature remains constant.

Why does temperature remain constant during melting and boiling?

because of phase transtion i.e. from solid to liquid during melting and from liquid to vapour during boiling. so just to change over from one phase to the other heat is totally utilized.


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 to the thermal energy of a substance during a physical change of state?

it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing

The heat of fusion is the amount of energy required to change 1 unit mass of a solid to a liquid at constant temperature.


The amount of heat necessary to change a liquid to a solid at constant temperature?

None - heat is evolved, not required.

Why liquid boils at constant temperature at a given temperature?

Yes.


Boiling liquid maintains a constant temperature?

The boiling point temperature remains constant because liquids evaporate at this point. If the temperature drops the liquid will no longer boil. At a higher temperature the vapor becomes hotter, not the liquid.
