Is nuclear waste solid, liquid or gas? What is its mass? Is it light enough to be dumped into space?
Q. What kind of types of forms does nuclear waste come in? Is it mostly solid / liquid / gas or are there different types? I'm mostly interested in nuclear waste produced by nuclear power plants. Also, what is its weight and volume? How is it created? Are there ways to avoid the creation of nuclear waste in nuclear power plants? Can nuclear waste be dumped into space relatively inexpensively? Also, to what extent does nuclear power pollute more / less than other forms of energy?

A. Space disposal is the ultimate solution to radioactive waste, but there are some problems associated with it. Nuclear waste is classified into several categories, including LL (low level), Intermediate level, and HLW (high level waste). Low level waste such as contaminated clothing, lab equipment, etc, is not too much of a problem. There is much more HLW, many thousand of tons per year, of solid nuclear waste consisting of spent fuel rods left over from fission reactions in power plants. The waste consists of highly radioactive, and long lived, isotopes of Uranium, Plutonium, Neptunium, Americium, Thorium, and Californium. There is also a lot of contaminated water as well, but most of the waste is solid. The biggest problem with sending… [cont.]

How do you know when an element is a solid, liquid, or gas?
Q. I have a chem test tomorrow and I need to be able to tell what element is a solid, a liquid, or a gas with out it being told to me. For example, could be given nitrogen, potassium, sodium, or chlorine and i'd have to know what physical state it's in. Is it related to if it's a metal or non-metal?
Asked by BreAnna - Thu Dec 11 19:48:12 2008 - - 2 Answers - 0 Comments

A. Yes you are right Metals (Group I to Group III) are solid because there are strong metallic bonding within the metal cations and the delocalised sea of electrons. Hence, a large amount of energy is needed to overcome these strong metallic bonds, hence, they have high melting point and they are solids. Non-metals are usually simple discrete covalent molecules with weak dispersion forces between the molecules. Only a small amount of energy is needed to overcome these weak dispersion forces. Hence, they have low melting and boiling points, they are liquid/gases. Under room temperature condition, mercury and bromine are liquids. Nitrogen, oxygen, chlorine, fluorine, hydrogen are gases. The rest most likely are solid.

Asked by bigbootyroxxanne - Thu Apr 5 17:04:23 2007 - - 3 Answers - 0 Comments

A. In solids - the molecules are very closely packed. Thats why there is no space for them to move around and this contrinutes towrds the factor of stiffness. In liquids - the molecules are comparatively lesser compressed than solids thats why they move around in freely motion and do not have a fixed shape and size. In Gases - the molecules are set much much apart and thats why they are ready and set to move in any direction. Thats why the gas is most compressible and it hasn tgot any shape. So for compressibility :- Solid > Liquid > Gas

Q. Compare the arrangement and speed of molecules in a solid, liquid, and gas?
Asked by Daiana - Tue May 19 19:59:35 2009 - - 4 Answers - 0 Comments

A. In a solid, the molecules are in the middle at the bottom of the element, and they are squished very tightly together, not moving which is why when you drop it, it doesn't spread out. In a liquid, the molecules are moving a little bit in the element, they are more spread out in the object and moving slightly, which is why when you drop it it will spread out. In a gas, the molecules are moving around very actively in the element, and they are very spread out, which is why a gas can fill up a whole room. When an element changes to these different phases of matter there are still the same amount of molecules in the element.

A. Dissolved: ions are usually surrounded by H2O molecules since H2O is polar and the ions are polar. Solid: Usually a 3D lattice of ions in various geometries like a cube, etc. Liquid: just a bunch of ions floating around.

A. Solid Snake was a clone made from big boss that was actually meant to be made. But liquid was actually all the left over stuff from solid snake. So basically Liquid Snake was a mistake. So naturally Liquid would hate Solid Snake. Also solid snake is the good guy and liquid is the bad guy. Just in case you didn't know, liquid did die in the first Metal Gear Solid but when ocelot got his arm chopped off (by Grey Fox) he took liquid's arm and put it on himself. This turned him into Liquid Ocelot, who has split personalities switching from Ocelot to Liquid time to time. Especially when he sees Solid Snake.

A. Agar is a polysaccharide. It dissolves in boiling water. It remains a solution when it is cooled to 65 degree Celsius. It solidifies when it is cooled below 45 degree Celsius, forming a gel-like substance. Once solidifies, it takes boiling to redissolve it again.

Is the transformation from liquid to solid exothermic or endothermic?
Q. The sample had to be cooled for the transformation to occur. I'm not sure, because if a sample is solid, doesn't that mean its intermolecular forces are stronger? So the reaction would be exothermic? But if a sample were liquid, then it has enough kinetic energy to overcome the intermolecular forces, so wouldn't the reaction be endothermic then, if it were going from liquid to solid (less kinetic energy) ? Is the reaction exothermic or endothermic then?
