# 5+ Quasi Static Process Example: Detailed Facts

In this article the topic of “Quasi static process example” will be discuss with quasi static process example related details. When the sliding friction force is work on that time it became irreversible.

5+ Quasi Static Process Example is listed below,

## In the daytime the expansion of railway tracks:-

In the thermodynamic the Quasi Static Process is defined as very slow process. Quasi Static Process appear infinitesimally slow.In the Quasi Static Process all the state stays in equilibrium. The expansion of railway tracks in the morning is one of the examples of Quasi Static Process. During the morning time the metal steel, cast iron  with which the railway track made of it absorb the heat and expansion is happened.

The expansion of railway tracks are happened in very slow process to avoid accident a certain amount of gap is present in between two railway tracks.

## Charging of Smartphone:-

Another example of the Quasi Static Process is charging of a Smartphone. During the charging of the Smartphone it takes a long time.  The Smartphone need to charge when is needed. But we should not fall below twenty percent or more than the twenty percent and fully avoid discharging the battery of the Smartphone if not calibration is needed. Should to unplug the Smartphone when the charge stays between eighty percent to hundred percent.

### Some process to make faster of the charging of Smartphone:-

1. Avoid wireless charging
2. A wall socket should be use
3. Turn the phone off
4. Should to carry a power bank
5. High quality cable should be use
6. Enable airplane mode
7. Case of the phone need to remove
8. Enable charge mode

## Growing of a tree:-

Growing of a tree is another example of the Quasi Static Process. Growing a tree takes a very long time and go through some stages of the life cycle. The states of the a life cycle are,

• Sprout (Germination)
• Seedling
• Sapling
• Mature Tree

### Sprout (Germination):-

When a seed could find appropriate condition the seed need to stable and secure its life itself. At the first of the state the roots are breaks from the seed. Anchoring it and takes water for grow of the tree. In the next step of the germination is takes place that it could emergence of the embryonic shoot.

After that the shoot grows up and pushes up by the soil.

### Seedling:-

The shoot is became a seed when it come above of the ground. In this stage the tree faces most risk because in this particular state the tree can faces dieses and also facing damage such as deer grazing. The trees which have long life span for them sapling became longer such as oaks, yews and in other way the trees which have short life span for them sapling became shorter such as wild cherry, silver birch.

### Sapling:-

A tree is called a sapling when it became near about 3 ft tall. The length of a sapling is totally depending on the family of the tree. Some characterises is carried by the sapling they are listed below,

• Flexible trunks
• Smoother bark comparative to the mature trees
• An inability to make flowers
• An inability to make fruits

### Mature Tree:-

A tree is called mature when it begins to make flowers and fruits. In the stage of producing flowers and fruits the tree stays at most productive state. Depend on the species the tree make flowers and fruits.

## Growing of hair:-

Growing of hair is another example of the Quasi Static Process. In this process hair takes time to grow and growing of hair is slow process. just like quasi static process.

## Growing of nail:-

Growing of nails is another example of the Quasi Static Process. In this process hair takes time to grow.

## Question: – Describe about the thermodynamic processes.

Solution: – A thermodynamic ring is a sequence of several processes. The thermodynamic process is start and ends at the very same thermodynamic state.

The thermodynamic processes are listed below,

### Isothermal process:-

When the system is undergoes to change from one state to the other state, but that time system does not change its temperature. The temperature of the system remains constant.

Thus, in our example of hot water in a thermos flask, if we remove a certain quantity of water from the flask but keep its temperature constant at 50 degree Celsius, the process is said to be an isothermal process.

### Isobaric process:-

When the system is undergoes to change from one state to the other state, but that time system does not change its pressure. The pressure of the system remains constant. The process is said to be an isobaric process.

### Isochoric process:-

When the system is undergoes to change from one state to the other state, but that time system does not change its volume. The volume of the system remains constant. The process is said to be an isochoric process.

The heating of gas in a closed cylinder is an example of an isochoric process.

The process during which the heat content of the system or a certain quantity of matter remains constant is called an adiabatic process.

Thus, in the adiabatic process, no heat transfer between the system and its surroundings occurs.

## Question: – Describe about the workdone by thermodynamic processes.

Solution: – The workdone by thermodynamic processes is done by foue proceeses, they are listed below,

### Constant temperature or Isothermal process:-

Where, Pressure express as p differ with volume express as v.

PV = P1P2 = C

So, W1-2 = P1V1ln(V2/V1)

### Polytropic process:-

W1-2 = (P1V1 P2V2)/n-1
