For one mole of any substance at its boiling point the difference in the enthalpy of its vapor is what?
Manthika
The change in enthalpy is dH = TdS + VdP. Since the pressure P is the same for the the vapor and the liquid, the change in enthalpy is just TdS, which is just the latent heat.

How does boiling point and melting point find a substance?
what is the melting point and boiling point of substance
Does gases have a boiling point?
Gas is a phase of a substance. Boiling is the point when a substance chains from liquid to gas. So if it is already gas, it has already reached the boiling point.
Boiling point of polar molecule?
The boiling point is specific for each substance.
What are the difference between freezing point and boiling point?

Temperature at which a substance boils?
Every substance has their own boiling point.

Is there a difference between freezing point depression and freezing point?
This is simply because the evaporation enthalpy is bigger than the enthalpy of fusion. ΔTf = -Kf · m (m= molality) ΔTb = Kb · m (m= molality) what is important is that Kf is proportional to 1/Enthalpy of fusion and the sam is true for Kb (with enthalpy of evaporation)
Is the boiling point of a substance an example of a chemical property?
The boiling point of a substance is an example of a physical property of that substance.
Is boiling point a chemical property in a substance?
Boiling point is a physical property not a chemical property.
What is the boiling point for celcious?
Celsius is not a substance and so does not have a boiling point
What is the substance of boiling point?
The boiling point of a substance is the temperature at which it changes from liquid state to gaseous or vapor state.
Does gases have a boiling point?
Gas is a phase of a substance. Boiling is the point when a substance chains from liquid to gas. So if it is already gas, it has already reached the boiling point.
What type of substance is a boiling point?
A boiling point isn't a substance at all. The boiling point of a substance is the temperature at which it changes from liquid to gas. For example, the boiling point of water at standard pressure is 100°C or 212°F. The boiling point of helium is -269°C or -452°F or 4.2K. The boiling point of iron is 2,862°C or 5,182°F.
