asked in category: General Last Updated: 18th March, 2020# Can you have a quadruple point in one component system?

**system**of three equations in two variables (T and P), the

**system**should

**have**no solution, and genuine

**quadruple points**should not occur in

**one**-

**component systems**.

Keeping this in consideration, what is the maximum number of phases that can be in mutual equilibrium in a four component system?

The **maximum number of phases that can** coexist in **equilibrium** is 3. At this point the degree of freedom of the **system** becomes zero. That is there are no independent variable remaining. In other words for this **system** to exist there will be a definite temperature, pressure and concentration.

Subsequently, question is, what is the maximum number of phases in equilibrium in 3 component system? 1 Answer. If there are **3 components**, using the formula, F=M+2-P and solving for P under **equilibrium** conditions there would be a total of 5 **phases**. I understand from that you set F=0. **Equilibrium** does not necessarily mean that you have no degrees of freedom.

Likewise, people ask, how can different phases coexist?

**We** constantly come across instances where various **phases** of a substance—such as gas, liquid, and solid—**coexist** with each **other**. These findings violate the Gibbs **phase** rule, which states that no more than three **phases** of a substance made from a single component **can coexist** at thermal equilibrium.

What are applications of phase rule?

It is a technique in which water is removed from the solid by heating it below . This technique is used in food stuff industry & pharmaceutical industry.
