What makes a gas what it is? ( AGW discussion)

It has no form. A solid has a form. A liguid can go to low places, and assume that form. But a gas has no place in particular to go. It has to be entrapped, or it goes all over the place. This is implied in the equation PV= nRT, where P=Pressure, V=Volume, n=number of molecules of a gas, R is a constant, and T=temperature.

You don't need such an equation for a solid. Just its dimensions.

But a gas needs to be measured by variables. The letters are variables in an equation. This implies changeableness. For liquids and solids, you can measure dimensions. How can you measure the dimensions of a gas? You cannot. It has no such thing.

For a thing that has no dimensions, how can it trap anything at all? But gases are said to trap heat. It isn't the gas that traps heat, it is the mass that traps heat. The more dense a substance is, the more capacity for heat retention. Don't believe that? Just note how long the kitchen stove stays hot after its heated up.

Let's look at another example. A black hole has a gravity well so deep that light cannot escape. Light is an electromagnetic wave. Heat is an electromagnetic wave. The thing that traps the heat and the light is the density of the matter in a black hole. Since a black hole is as dense as matter can get, it is prime example of how matter traps heat ( and everything else).

Check out this video. It is how gravity bends light.







AGW is bunk because gases cannot trap heat, or anything else. A gravity well can. Chemical reactions may affect heat absorption. Dense materials can, if there's enough mass. But a few parts per million in the atmosphere? No frickin' way.
