What is true about the temperature of melting point and boiling point?

Under ordinary conditions they are the same 'point'. For example, water just freezes and it just melts at zero degrees centigrade. The difference between the two states is not temperature, but the heat of fusion. When the heat of fusion is removed from water at zero degrees, it will freeze. When the heat of fusion is added to ice at zero degrees, it will melt.

What is true of a melting point and a boiling point?
Melting point is a temperature in which solid change into liquid form and boiling point in which liquid convert into gas form
Why fast rate of heating gives higher melting and boiling point than the true one?
Because the temperature is higher hence make the boiling and melting point higher.
Is it true that particles can only evaporate from a liquid at temperatures above liquids boiling point?
It is not true; evaporation occur at the surface of a liquid and the temperature is under the boiling point.
Is this statement true or false saturated fats tend to be solid at room temperature while unsaturated fats tend to be liquid oils at room temperature?
True. Saturated fats have a higher melting point and tend to be solid at room temperature, while unsaturated fats have a lower melting point and are typically liquid oils at room temperature.
What are some properties you can identify by knowing the melting and boiling point of chemical?
Melting and boiling points are generally higher for large molecules than small, and also higher for polar than for non-polar molecules.
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.

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".
Weak dipole-dipole forces result in a what melting point?
The stronger the bonds between molecules; the higher the melting/boiling points. This makes sense if you think about it, melting/boiling is splitting up the molecules - the stronger they are bonded the more energy you will need
Is it true that particles can only evaporate from a liquid at temperatures above liquids boiling point?
It is not true; evaporation occur at the surface of a liquid and the temperature is under the boiling point.

True. Saturated fats have a higher melting point and tend to be solid at room temperature, while unsaturated fats have a lower melting point and are typically liquid oils at room temperature.
What are the melting points of Copper and its alloys?
CopperMelting point: 1357k (1084.62 C / 1984.32 F)Boiling point: 3200k (2927 C / 5301 F)Pure copper melts at 1080C.is this true?
Is it true that in fractional distillation of petroleum low-boiling hydrocarbons come out first?
Yes Since they have a lower boiling point, they have a higher vapor pressure - or to be more exact, a higher fugacity, than the higher boiling point components at the same temperature.
Is it true that a liter of gasoline will boil at the same temperature as a milliliter of gasoline?
Yes, as boiling point is a property of the substance.
What requires more energy melting or boiling?
Melting requires energy input or absorption because liquid water has more energy than solid water.
What are some properties you can identify by knowing the melting and boiling point of chemical?
Melting and boiling points are generally higher for large molecules than small, and also higher for polar than for non-polar molecules.
