StarCraft M and Ms. It's simply a bunch of Marines and Medics and can win the entire game if enough of them are used. Basically the same thing as the Zerg Rushwhich also counts as Simple, yet Awesome. The sequel replaces this with Marines and Marauders.

We want now to discuss what happens when things are near, but not exactly in, equilibrium. In a situation far from equilibrium, things are extremely complicated, but in a situation very close to equilibrium we can easily work out what happens.

To see what happens, we must, however, return to the kinetic theory. Statistical mechanics and thermodynamics deal with the equilibrium situation, but away from equilibrium we can only analyze what occurs atom by atom, so to speak.

As a simple example of a nonequilibrium circumstance, we shall consider the diffusion of ions in a gas. Suppose that in a gas there is a relatively small concentration of ions—electrically charged molecules.

If we put an electric field on the gas, then each ion will have a force on it which is different from the forces on the neutral molecules of the gas.

If there were no other molecules present, an ion would have a constant acceleration until it reached the wall of the container. But because of the presence of the other molecules, it cannot do that; its velocity increases only until it collides with a molecule and loses its momentum.

It starts again to pick up more speed, but then it loses its momentum again. The net effect is that an ion works its way along an erratic path, but with a net motion in the direction of the electric force.

While the field is on, and while the ion is moving along, it is, of course, not in thermal equilibrium, it is trying to get to equilibrium, which is to be sitting at the end of the container.

By means of the kinetic theory we can compute the drift velocity. It turns out that with our present mathematical abilities we cannot really compute precisely what will happen, but we can obtain approximate results which exhibit all the essential features. We can find out how things will vary with pressure, with temperature, and so on, but it will not be possible to get precisely the correct numerical factors in front of all the terms.

We shall, therefore, in our derivations, not worry about the precise value of numerical factors. They can be obtained only by a very much more sophisticated mathematical treatment. Before we consider what happens in nonequilibrium situations, we shall need to look a little closer at what goes on in a gas in thermal equilibrium.

We shall need to know, for example, what the average time between successive collisions of a molecule is. Any molecule experiences a sequence of collisions with other molecules—in a random way, of course.

If we double the length of time, there will be twice as many hits. We would like to write it this way: We may often wish to ask the following question: But let us try to make a more convincing argument.

If there is equilibrium, nothing is changing on the average with time.

A particular particle does not have a collision, wait one minute, and then have another collision. The times between successive collisions are quite variable. We will not need it for our later work here, but we may make a small diversion to answer the question: We shall find the answer to the general question: Making this substitution, Eq.

The chance is less than one-half that it will have a greater than average time between collisions. The result we have obtained in Eq. We can demonstrate this somewhat surprising fact in the following way. This distance between collisions is usually called the mean free path:Science.

Watch the video on chlorine.; Cut out and fill in your chlorine piece. Chlorine is part of the halogens or florine family; Art. Draw your pictures (at least five) that together tell your story. Sometimes the simple solutions are the best ones.

Though the best solutions are sometimes the boring ones, occasionally they achieve a sort of elegance that keeps them from being kaja-net.comgh lacking the over-the-top badassery and flashy visual effects that would make it Awesome, but Impractical, their very simplicity gives them a sort of awesomeness all their own.

Generic Physical Superpowers. Superstrength. The mean free path or average distance between collisions for a gas molecule may be estimated from kinetic theory. Serway's approach is a good visualization - if the molecules have diameter d, then the effective cross-section for collision can be modeled by using a circle of diameter 2d to represent. You don’t need a “heat energy source” to raise temperature. All you have to do is reduce the rate of energy loss. That’s why the core of the sun only produces a fraction of the heat energy the human body does (per kg of mass), yet has an estimated temperature of millions of degrees.

Kinetic Theory of Gases Page cIn this text, as in many others, we will use the notation or x to mean "the average value of x. dThroughout the text we will use boldface symbols to indicate vector quantities and normal weight symbols to indicate scalar quantities.

X-ray crystallography is a technique used for determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions.

By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal.
