Please describe to me the laws of thermodynamics. There are a certain number of them and therefore you must have all of them. Each should be labeled with it's number. For instance "The First Law of thermodynamics says that..."
A system's "entropy" is
(a) the amount of work the system can do.
(b) the amount of microscopic work the system can do.
(c) the amount of force the system could exert.
(d) the amount of thermal energy in the system.
(e) the amount of microscopic disorganization in the system.
In the simple kinetic theory of a gas we discussed in class, the molecules are assumed to be point-like objects (without any volume) so that they rarely collide with one another. In reality, each molecule has a small volume and so there are collisions. Let's assume that a molecule is a hard sphere of radius r. Then the molecules will occasionally collide with each other. The average distance traveled between two successive collisions (called mean free path) is λ = V/(4π √2 r2N) where V is the volume of the gas containing N molecules. Calculate the mean free path of a H2 molecule in a hydrogen gas tank at STP. Assume the molecular radius to be 10-10
a) 2.1*10-7 m
b) 4.2*10-7 m
c) none of these.
