Compressed gases aren't ideal. Let's consider a gas that's non-ideal only because the volume available to each of the N molecules is reduced because each other molecule occupies volume v. Instead of PV=NKT, we get: P(V-NB)=NKT. Let b=1.2 x 10-28 m3.
Let's look at 3moles of this gas at T=300K starting in 0.001 m3 volume.
1) What's the initial value of the pressure? Pinitial= Pa
2) The gas expands isothermally to 0.002 m3.What's the final pressure? Pfinal= Pa
3) How much work did the gas do in this isothermal expansion? W= J

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
