Work done in a thermodynamic process

In summary, "Work done" is the transfer of energy during a thermodynamic process, calculated using the formula W = F * d. It is different from heat, which is a form of energy transfer through temperature difference. "Work done" is related to the first law of thermodynamics and can affect the efficiency of a process.

Homework Equations

The Attempt at a Solution


The work done is maximum in the path (3) as the area covered by this path is maximum.

Now, dU = dQ + dW, the work done is minimum in the Path (1) , so dQ should be maximum.

Hence, the correct options are A and C.

Is this correct?

Related to Work done in a thermodynamic process

1. What is "work done" in a thermodynamic process?

"Work done" refers to the transfer of energy from one form to another during a thermodynamic process. It can be thought of as the force applied to move an object over a distance, resulting in a change in energy.

2. How is "work done" calculated in a thermodynamic process?

The formula for calculating work done in a thermodynamic process is W = F * d, where W is work, F is the force applied, and d is the distance over which the force is applied.

3. What is the difference between "work done" and "heat" in a thermodynamic process?

While both "work done" and "heat" involve the transfer of energy, they differ in their methods of transfer. Work is done through a mechanical process, such as pushing or pulling, while heat is a form of energy transfer through a temperature difference.

4. How is "work done" related to the first law of thermodynamics?

The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted. "Work done" is one way in which energy can be transferred from one form to another, and thus is directly related to the first law.

5. How does "work done" affect the efficiency of a thermodynamic process?

The amount of "work done" in a thermodynamic process can affect the efficiency of the process. In an ideal thermodynamic process, all of the work done would result in a change in energy, but in reality, some energy is lost as heat. The less work done, the less efficient the process is.
