Re: [Phys-l] T dS versus dQ

I'll go back and try that on one. We have a dozen setups and I always thought the stiffness was a "feature" to keep everything isothermal :-)

Have you tried grease?

I'd replace the shaft w/ an unthreaded one and add a sleeve to the top
plate, so one may even do "mixing" in addition to quasi-adiabatic
compression (rarefaction).

Maybe ours are just stiffer than yours to turn.
