boiling points

[Clarissa Nava 3H]

when reaching a boiling point in a heating curve does that mean it is already getting vaporized?

[Michael Torres 4I]

To get vaporized, a substance must undergo some enthalpy of vaporization at the boiling point. Therefore, simply being at the boiling point is not enough to vaporize a substance.

I found this diagram online which will hopefully help clarify things. You can see that it takes some time before the liquid is fully vaporized.

You can see from the graph that there is a moment where the water begins to boil and the temperature stays the same while heat is still being supplied. This is the phase change occurring but the vaporization is not seen until the temperature on the graph begins to rise.

It begins to vaporize when the temperature reaches the boiling point. It stays at that temperature until it's completely vaporized.
