The triple point of a substance is the temperature and pressure conditions at which?
... the substance can exist in the solid, liquid, and gaseous phases all at the same time.
What is Celsius triple point?
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.https://en.wikipedia.org/wiki/Triple_point
What are the three phases of matter in the case of water?
It is not entirely correct to talk about "the" three phases. There are actually more than three phases of matter. In the case of water, the three "main" phases are called: "ice" (for solid water), "liquid water" or just "water" for the liquid phase, and "water vapor" for the gaseous phase. In the case of water, and many other substances, there is also a "supercritical" phase (among others). I don't think this one has a special name, in the case of water. The supercritical phase is used for dry cleaning; although it is more common to use carbon dioxide for this purpose, since it requires less temperature and pressure.
When a substance freezes what causes the liquid phase to change into the solid phase?
When a liquid is cooled, the average energy of the molecules decreases. At some point, the amount of heat removed is great enough that the attractive forces between molecules draw the molecules close together, and the liquid freezes to a solid. Microscopic view of a liquid. Microscopic view of a solid. The temperature of a freezing liquid remains constant, even when more heat is removed. The freezing point of a liquid or the melting point of a solid is the temperature at which the solid and liquid phases are in equilibrium. The rate of freezing of the liquid is equal to the rate of melting of the solid and the quantities of solid and liquid remain constant.
What are those phases of matter?
Matter has 4 phases; solid, liquid, gas and plasma.
Can ice and boiling water exist at same temperature?
Yes. In fact, there is a specific combination of pressure and temperature where the solid, liquid, and gaseous phases can co-exist. Do some reading on "triple point".Yes.

What phases are in equilibrium at a substance's melting point?
Evaporating and condensing
The triple point of a substance is the temperature and pressure conditions at which?
... the substance can exist in the solid, liquid, and gaseous phases all at the same time.
What factors affect the vapour pressure of a liquid?
Vapor pressure or equilibrium vapor pressure are the pressure of a vapor in thermodynamic equilibrium with its condensed phases in a closed bottle. All liquids and solids have a tendency to evaporate into a gaseous form, and all gases have a tendency to condense back to their liquid or solid form.The equilibrium vapour pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapour pressure at normal temperatures is often referred to as volatile
Why the freezing point of liquid is same as melting point of solid?
The freezing point and melting point of a substance are both defined as the temperature at which liquid and solid phases of the substance can remain together at equilibrium.
What is represented at triple point of water?
solid, liquid, gas phases in equilibrium
How are the conditions pressure and temperature at which two phases coexist in equilibrium shown on a phase diagram?
By a line separating the phases
How are conditions of pressure and temperature at which two phases coexist in equilibrium shown on a phase diagram?
By a line separating the phases.
What does the line spearating the solid phase from the vapor phase represent?
The line represents the set of all temperature- pressure values at which the liquid and gas phases of the H20 are in equilibrium.
When is water in equilibrium with water vapor?
When the concentration of the liquid (water) and gas (vapor) phases do not change.
Equilibrium constant for water Kw?
At a constant 100 C and 1 ATM ambient pressure, I believe it should be 1 as the gaseous and liquid phases would be equally favored. This is due to the fact that the vapor pressure of liquid water at 100 C is 1 ATM.
What is the the triple point on a phase diagram?
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.
