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.

Chemical energy is a form of energy. a. heat b. kinetic c. potential d. electromagnetic

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

An architect plans to use solar energy to heat the next house he designs. what principle of absorption and infrared energy can be applied to the design of the new house? how could she apply to those principals?
