Homework Statement Is this impossible: (yes or no) During an adiabatic process, 37 J of work was done on the system. Homework Equations Delta U=-W The Attempt at a Solution I think it is impossible because it says work is negative. I am not sure though.

I asked my teacher about a vacuum chamber today and he said that it contains no air and thanks for the other one I understand it now

well a vacuum chamber has no air, so would it be 0 K meaning their is no motion in the particles... so the vacuum one would be impossible too? My other question is: is this possible: A substance underwent melting during which its temperature remained constant at 33 °C

Homework Statement Which of the following statements are IMPOSSIBLE? Choose all that apply. ___A perfectly functioning hydraulic had a pressure of 36 Pa in the fluid near the small piston and a pressure of 37 Pa in the fluid near the big piston. ___A 35 L container displaced 42 L of...

isobaric means same pressure but i tried 429 and that didnt work Is the difference in pressure 0? so 0 would be delta p?

Homework Statement Pf 429 Q -754 ΔU 819 The table above shows the measurements taken while an ideal gas underwent an ISOBARIC process. Fill in the appropriate values for the table below. ΔP=? Homework Equations Q= ΔU+W=ΔU=PΔV The Attempt at a Solution I don't know how to go...

thank you so much!

Homework Statement A 1575 Hz wave is passing through a medium and has a speed of 823 m/s. How fast would a 163 Hz wave travel through the same medium? Assume both waves are the same type and that the medium doesn't change in any significant way. Homework Equations...
