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.

The material that keeps its new shape after it is stretched is called?

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
