We derived the ideal gas law using the fact that for an ideal gas, s=nrln(v)+ const and p/t= ∂s/∂v (try it you will get pv=nkt). compute an equilibrium condition for an almost ideal gas, for which
s=nrln(v-nb)+const and use it to answer the equation below:

1. suppose that
b=8x10^-4 m^3/mole
n=30.2moles
v=1m^3
p=101300pa

2. what is the temperature

3. suppose that
b=8x10^-4 m^3/mole
n=1.5 moles
t=350k
p=101300pa
what is the volumn.

part 1: describe the mass and the surface temperature of dwarf stars.

part 2: explain using complete sentences where on the hr diagram you would expect to find a dwarf star based on its physical properties.

part 1: the mass of a dwarf star is very small and the surface temperature of dwarf stars are high and they have the lowest absolute brightness.

part 2: on the hr diagram you would expect to find a dwarf star based on its physical properties at an absolute brightness of -2 to -4

hope this
