Is boiling point is always same as the melting point?
No, the boiling point and the melting point are not always the same. The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid.
Do all liquids have the same boiling and melting point?
No, different liquids have different boiling and melting points depending on their chemical composition. The boiling point is the temperature at which a liquid turns into a gas, while the melting point is the temperature at which a solid turns into a liquid. Each liquid has its own unique set of physical properties that determine its specific boiling and melting points.
Is freezing boiling or melting most affected by pressure?
Boiling point is most affected by pressure. Note that freezing point and melting point are in fact the same.
Why is the melting and boiling point of carbon dioxide the same -78degree?
They aren't the same. The boiling point of carbon dioxide is -57 oC. (Wikipedia)
Is boiling point higher than melting point?
The boiling point is typically higher than the melting point for a substance. The boiling point is the temperature at which a substance transitions from a liquid to a gas, while the melting point is the temperature at which a substance transitions from a solid to a liquid.
Why does the temp stay the same when boiling and melting?
The temperature stays the same during boiling and melting because the heat energy is being used to break intermolecular forces rather than raise the temperature. During boiling, this energy is used to convert the liquid into vapor, while during melting, it is used to convert the solid into a liquid.
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".
Is melting point the same as its boiling point?
No. The boiling point is higher temp. than the melting point. When something is melted, it becomes liquid: when something is boiled, it begins to become vapor.
Does melting and boiling cause physical changes?
Melting and boiling are physical changes.
How can the melting and boiling point help you identify it?
Melting and boiling points are physical properties unique to each substance, so knowing these values can help identify a substance. By comparing the observed melting and boiling points of an unknown substance to known values in a database, you can narrow down the possible identities of the substance. Substances with similar melting and boiling points are more likely to be the same compound.
What is hydrogen's melting and boiling point?
Melting: -259.14 C Boiling: -252.87 C
Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
