At the triple point for the substance. At that particular temperature and pressure you have solid, liquid and gas existing at the same time, so it will "boil" (become a vapor) and freeze (become a solid) at the same time.
Six
Zero degrees C= Freezing temperature for water and one hundred degrees C= Boiling temperature for water.
There isn't any but if you mean freezing of 32 degrees and boiling of 212 degrees then it is the Fahrenheit temperature scale.
Boiling point is the temperature at which a liquid changes into a gas. Freezing point is the temperature at which a liquid changes into a solid.
Freezing = 0 Boiling = 100
freezing= 0 boiling= 100
Boiling point: the temperature when a material become a gas phase.
Melting (freezing) point: the temperature when the solid metal become a liquid. Boiling point: the temperature when the liquid metal become a gas.
The Celsius temperature scale has 100 degrees between freezing and boiling.
It is the temperature at which the vapor prussure of a liquid is equal to the standard atmospheric pressure (1 atm = 760 torr). Boiling point: the temperature of the phase change from liquid to gas. Melting point: the temperature of the phase change from solid to liquid.
Pure water has a freezing temperature of 0 degrees and a boiling temperature of 100 degrees, unlike tap water which has impurities that can alter it's freezing and boiling point
It is constructed with 0 as the freezing temperature of water, and 100 as the boiling temperature.
