Work without volume

[Abigail Menchaca_1H]

Can we calculate work without knowing change in volume?

[TimVintsDis4L]

I don't know if this really helps, but if we are given the Internal Energy, q, or things that can be used to find q such as and t, then we can find q using . Once you find the q, you can plug it into to get w.

The only types of work we need to know for thermodynamics are expansion work and non-expansion work, which involve volume change.

[Sreyes_1C]

since what we learned involves expansion of volume, we need the change in volume to see how much work is done

[Chloe Alviz 1E]

I think most of the problems that we do involve expansion work (so a change in volume is given), but since you can relate work with U = q + w, I assume you can find it through this equation given the internal energy and enthalpy.

[Ryan Yee 1J]

Since w=p(deltaV), not knowing the volume would mean you cant calculate work. But since U= q + w, given internal energy and enthalpy, you could calculate work.
