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=7 × 10^-29 m3. let's look at 3 moles of this gas at t=300k starting in 0.001 m3 volume.
1) what's the initial value of the pressure? p_initial = ?
2) the gas expands isothermally to 0.002 m3. what's the final pressure? p_final = ?
3) how much work did the gas do in this isothermal expansion? w = ?

Athin, square metal plate measures 14 cm on each side and has emissivity of 0.60. the plate is heated to a temperature of 745°c. what is the rate at which the plate radiates energy ? the stefan-boltzmann constant is 5.67 × 10-8 w/(m2 ? k4). remember that the plate will radiate energy from both its top and bottom surfaces.
