We found the chemical potential of an ideal gas by differentiating the helmholtz free energy with respect to particle number, at constant temperature and volume. now find the chemical potential of an ideal gas by differentiating the energy with respect to particle number, at constant entropy and volume.

Which is an example of gaining a static charge by conduction? a) rubbing a balloon against your hair. b) shuffling your shoes across a carpet. c) bringing a charged rod near an electroscope. d) touching your car on a cold day and getting a shock.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
