The energy must be applied to the phase change before it can heat the substance

Are melting and boiling points of a substance the same?
The melting and boiling points of a substance (in this case I am assuming you are referring to a pure substance, and not a mixture), are the same. The triple point is defined by the temperature and pressure at which solid, liquid, and vapor of a substance, can coexist in equilibrium. At any pressure below the triple point, only sublimation and condensation are possible (no liquid phase is possible). Between the triple point pressure and the critical point pressure, there is a difference between the melting and boiling points, of a substance. The melting point temperature will be lower than the boiling point. At the critical point, the densities of the liquid and vapor phases, have merged, and boiling no longer occurs. At and above the critical point, you cease to get liquid and vapor, but you get what is referred to as a "supercritical fluid".
Does chlorine have a high melting point low boiling point etc?
low melting point, it is a gas at room temperature....
How can iodine have a melting point?
All substances have melting points and boiling points. A melting point is merely the temperarture at which it changes from a solid to liquid and vice versa. The boiling point of a substance would be the temperature at which it changes from liquid to gas and vice versa.
What is the lowest Melting point of copper in kelvin?
The boiling temperature of copper is 2 835 K.
Is the boiling point of something the same as the melting point?
The boiling point is the temperature at which the vapor pressure of the liquid is equal to the external pressure. It is also the condensation point. The freezing point is the temperature at which liquid and solid coexist in equilibrium. It is also the melting point.
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 are 5 liquids that do not have water?
-- pure alcohol at room temperature -- mercury at room temperature -- oxygen below its boiling temperature -- iron above its melting temperature -- nitrogen below its boiling temperature -- salt above its melting temperature -- gold above its melting temperature -- any other element or compound that is not H2O, above its melting temperature and below its boiling temperature
What is melting points and the boiling points?
Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.
What is the boiling melting and freezing point?
A boiling point is a point on the temperature scale at which a substance begins to boil. A melting point is a point on the temperature scale at which a substance freezes. Melting and boiling points are unique to different types of elements.
What do boiling point and melting point have to do with the phase of matter of an element at room temperature?
The state of matter of a substance at room temperature depends on whether the melting and boiling points are above or below room temperature. At room temperature:A substance is solid if both the melting and boiling points are above room temperature.A substance is liquid if the melting point is below room temperature but the boiling point is above room temperature.A substance is a gas if both the melting point and boiling point are below room temperature.
How can you use boiling points and melting points to determine a solid liquid or gas that an element would be in at a certain temperature?
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
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.
What is the melting and boiling temperature for protactinium?
Protactinium:- melting point: 1 568 0C- boiling point: 4 021 0C
Which is true of a melting point and a boiling point?
Melting point: at this temperature a solid become a liquid.Boiling point: at this temperature a liquid become a gas.
How can information about the melting point and boiling point of matter help you know its states?
If the temperature is below the melting point, you know it is in the solid state. If the temperature is below the boiling point, and above the melting point, you know it is a liquid. If the temperature is above the boiling point, you know it is a gas, etc. (Note: melting point is the same as freezing point).
Is boiling point is always same as the melting point?
NO!!! Boiling point is the temperature when a liquid changes to a gas. Melting point is the temperature when a solid changes to a liquid. Remember For rising temperatures It melts then boils For falling temperatures It condenses then freezes. Melting/Freezing point is the same temperature for change of state solid/liquid Boiling/Condensing point is the same temperature for change of state liquid/gas
What is the melting and boiling point of ice?
any temperature above zero.
