The boiling point of any given liquid will remain constant as long as the air pressure remains constant. Ambient air pressure or any other pressure on the liquid will affect the boiling point. In a vacuum, everything boils at a lower temperature.
This is true, and this is why: The boiling point is the temperature where liquid converts itself into gas. Once you reach that temp, the energy that was being used to raise the temp of the liquid is redirected to causing phase change.
Once all the liquid has undergone phase change, any added energy will be used to increase the temp of the vapor...there are plenty of industrial uses for 600-degree "superheated steam."
The chemical composition of water remain unchanged.
The shape of a molecule of water, H2O, is
Melting Point
Terbium melts at 1629 Kelvins. Therefore, it is solid at room temperature.
A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
I am pretty sure that it is the temperature which is applied to the substance. For example when heat is applied to a solid it melts, causing it to change from one phase to another. Also when a liquid freezes the temperature drops and it converts into a solid.
Solid. Boron melts at 2076 C
When a solid melts, it is due to an increase in thermal energy to the temperature at which it melts.
it melts
melting point
Melting Point
The temperature at which intermolecular forces push the molecules apart
By heating the internal energy of a solid increase what leads to melting when the crystalline system is destroyed and the solid become a liquid.

At room temperature, Nickel is in its solid state. Nickel (Ni) melts at 1453ºC and boils at 2732ºC.

Tellurium is a solid at room temperature. It melts at 449.51 degrees Celsius (841.12 degrees Fahrenheit) and boils at 988 degrees Celsius (1810 degrees Fahrenheit).
