In this exercise, we will investigate the chemical potential μ upon a change in volume. we will use the fact that f=u−ts and μ=∂f∂n. we will compute μ(vf)−μ(vi) in all questions, take n=20 moles (which is 20 times avagodro's number of particles), t=300 k, vi=0.01 m3,vf=0.02 m3 1) for a gas with an excluded volume: u=32nkt+const s=nkln(v−bn)+const if b=10-28 m3, compute μ(vf)−μ(vi)

How does an observation about an object differ from an inference about that object

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
