The triple point of a substance is the temperature and pressure at which the three phases (gas,liquid, and solid) of that substance coexist in thermodynamic equilibrium. The triple point of water is 0.01 degrees Celsius and 0.00603659 atm. At that point, all of the substance can be changed into a liquid, solid, or gas by making small changes in temperature and pressure.

273.16 K (0.01oC), 611.73 Pa (about 0.006 atm).
The freezing point of water in Celsius is 0 degrees.
The freezing point of water on the Celsius scale is 0 degrees Celsius.
The freezing point of water in Celsius is 0 degrees.
The freezing point of water on the Celsius scale is 0 degrees Celsius.
The triple point of water is zero degree Celsius this is because 1)zero degree Celsius is the melting point of ice. 2)water changes from liquid to solid in zero degree Celsius.
The triple point refers the temperature and pressure at which the three phases of silver coexist in the thermodynamic equilibrium. The triple point of silver is 1233.95 degrees Celsius.
In triple point,all phases of water, vapour,Liquid water and ice is @ equilibrium.
The temperature at which all three phases of a substance can exist in equilibrium. This temperature occurs at only one pressure.
The triple point for benzene is the temperature and pressure at which benzene can exist simultaneously as a solid, liquid, and gas. For benzene, the triple point occurs at a temperature of 5.5 degrees Celsius and a pressure of 48.6 kilopascals.
The freezing point of R-12 ( Dichlorodifluoromethane, a form of Freon) is −157.7 °C.
Boiling point: 100 0C Freezing point: 0 0C (and 0,01 0C based on the triple point of water)
triple point of water is chosen as standard fixed point because in this point it represent a unique value of pressure and temperature at which solid,liquid,gases states of the substance are equally stable and co-exist.
The triple point of a phase diagram is the location where the solid, liquid, and gas phases meet; it is the temperature and pressure at which a given substance can assume any of the 3 usual phases of matter.
The base unit for temperature is the Kelvin. Kelvin takes as its zero point absolute zero (-273.15oC). A kelvin is defined as 1/273.16 of the temperature of the triple point of water, triple point is the temperature and pressure where a substance can exist as solid, liquid, and gas at equilibrium, for water this temperature is 0.01oC. This means that one kelvin is the same size as one degree Celsius, or temperature in Celsius is temperature in kelvin+ 273.15. Most non-technical temperatures are expressed in Celsius.
