Calculating Work Done by a Gas Using the PV=1000 Equation | Thermo Help

In summary, "Pv concept stuck on this one" is a phrase used by scientists to describe a situation where they are struggling to understand or find a solution to a particular concept or problem related to photosynthetic efficiency. It is common for scientists to encounter difficulties in their research related to Pv due to its complexity and various factors that can affect it. To overcome being stuck on a Pv concept, scientists often collaborate, consult with experts, conduct further experiments, and analyze their data more closely. Getting stuck on a concept is not a sign of failure in scientific research, but rather a common part of the process that can lead to new discoveries and insights.

A gas expands according to the equation pv=1000. where p is pressure in kPa and v is specific volume m^3/kg. If the gas pressure drops from 1000 to 500kPa, how much work was done by the gas??

Ok I am new to thermo and given a question and can't figure it out.
Do I use net flow work = p2v2-p1v1??
Answer is 693.1 kJ/kg.

or is it w-p delta v?
I am not sure.
Any help or direction would help thanks

Start from
work = force x displacement
BUT remember that the force is not constant.
 

1. What does "Pv concept stuck on this one" mean?

"Pv concept stuck on this one" is a phrase used by scientists to describe a situation where they are struggling to understand or find a solution to a particular concept or problem related to Pv (photosynthetic efficiency). It indicates that they are facing a roadblock in their research or understanding of the subject.

2. How common is it for scientists to get stuck on a Pv concept?

It is quite common for scientists to encounter difficulties or challenges in their research related to Pv. This is because photosynthetic efficiency is a complex process that is still not fully understood, and there are many factors that can affect it. Therefore, it is not uncommon for scientists to get stuck on a particular concept or aspect of Pv.

3. What are some possible reasons for getting stuck on a Pv concept?

There can be various reasons for getting stuck on a Pv concept. Some common reasons include lack of data or information, technical limitations, conflicting results, and insufficient understanding of the subject matter. Additionally, the complexity of Pv and its dependence on various environmental factors can also contribute to getting stuck on a particular concept.

4. How do scientists overcome being stuck on a Pv concept?

To overcome being stuck on a Pv concept, scientists often collaborate with other researchers, consult with experts in the field, and conduct further experiments and studies. They may also analyze their data and results more closely, and use different analytical techniques to gain a deeper understanding of the concept. It may also require exploring new approaches and methods to tackle the problem.

5. Is getting stuck on a Pv concept a sign of failure in scientific research?

No, getting stuck on a Pv concept is not a sign of failure. In fact, it is a common part of the scientific process and can lead to new discoveries and insights. It shows that the scientist is actively engaged in their research and is striving to understand the subject matter more deeply. Getting stuck on a concept can also lead to new research questions and avenues for further exploration.
