The internal energy of an expanding gas changes by 2000j. How much work is done if the process is done adiabatically?

Sagot :

Given

The internal energy of an expanding gas changes by U=2000J.

To find

The work done

Explanation

Since the work done is adiabatic so the change in heat is zero.

By first law of thermodynamics,

[tex]\begin{gathered} U=Q+W \\ \Rightarrow2000+0+W \\ \Rightarrow W=2000J \end{gathered}[/tex]

Conclusion

The work done is 2000J
