is the compression of gas product favored? is energy more dispersed?

Le Chatelier's principle will state that gas compression is favored if pressure is increased.  But when talking about energy dispersion, all materials favor greater entropy or greater chaos.

When gas is compressed in a thermally insulated vessel the gas is heated.\n\nWhen pressure increases temperature increases.\n\nSimilarly if the gas is expanded in a thermally insulated vessel the gas is cooled.\n\nWhen the pressure decreases the temperature decreases. \n\nNear earth’s surface, the atmospheric pressure is very high.\n\nAt a height of 30km from the surface, the pressure of air is almost zero.\n\nThough the hot air goes up; as it goes up the pressure decreases and volume increases (density decreases) and as per the  gas equation the temperature decreases.

It is Boyle's law & Charle's Law combined\nVolume of a gas is inversly propotional to Temprature & Pressure.\nOn Cooling can the Pressure & volume is decreased on can\nSince the outer layer of can feels pressure of air & it is more than inner pressure of can So it is crushed

Yes gravity has effect on gas molecules.\n\nNewton's Law of Gravitation governs the attraction between earth and the gas molecules. It is similar to solid or liquid molecules. However the density (mass per unit volume) incase of gases is very low so the attractive force is not easily felt.\n\nGoing up or down of gas molecules is governed by two other factors.\n1. The kinetic energy of gas molecules is so high that the gas molecules easily move in all directions, but to a certain limit thus the gas molecules also move up.\n\n2. When there are mixtures of different substances the heavy molecules are more affected by the gravity and so they remain close to the earth and the light molecules settle above. This applies to all states of matter e.g. wood flots on water.

It is generally said that the law of conservation of mass holds for ordinary chemical reactions, and for all intensive purposes, it does.\nHowever, technically, there is a VERY small change in the mass (too small to even matter to most things) when energy is given off or gained.\n\nIn the case of 56 kJ being released when 1 g of natural gas combusts, there is an associated change in mass of only 6.2 E-13 kg (6.2 E -10 grams).\nE = mc^2\n56000 Joules = m (3 E8)^3\nm = 56000 / (9 E16)\nThis is such a small number, it is very easy to ignore it as it would be near impossible to measure such a small amount anyway.

Sound travels faster through denser materials.  The closer the molecules of the material are, the easier it is for them to pass the sound energy between them.\n\nSolids are the densest of the three, then liquids, then gases.

It would definitely depend on the gas used. Some gases are heavier than air and would fall istead of rise. Consider also the pressure inside the ballon. It may rupture with the decrease in atmospheric pressure.\nToo many variables to give you a proper answer.

a) \n\nThe molecules in a substance are in constant motion. Now there are two oppposing forces on a substance. One is the intermolecular bond energy that tries to keep the molecules together. The other is the kinetic energy of the molecules that tries to push the molecules apart (these two forces work together to keep substances in equilibrium - basically keeps it from exploding or imploding in simple terms).\n\nNow, in solids, the molecules have low kinetic energy but high intermolecular bond energy(IBE). Liquids, the kinetic energy is higher and conversely the IBE is lower. Gases, the kinetic energy is high and the IBE is low (makes sense - the "bond" is weak)\n\nSo now, the kinetic energy or molecules is directly proportional to the heat applied - the hotter it is, the more kinetic energy the molecules have. Therefore when you heat it ... the kintic energy gets stronger and stronger and the IBE gets weaker and weaker until it breaks and the substance undergoes its change of state.\n\nHope this explained it well!

Strictly speaking, it is not true.  CO2, being heavier than air, WILL accumulate on ground level, if the air is perfectly still for a long enough period of time.  Or if the CO2 gas is colder than the air.  \n\nKeep in mind, though, that since the molecular weights of CO and of air are pretty close, the relative rate of diffusion of CO in air will be fairly slow.  That means if you have something making CO and putting it into the air, the worst place to be is right next to it.  Especially if the air is still.

well, others might have told you it is pressure, and actually even i would have gone for it!\nbut since you have mentioned in particular on a fluid, then this ratio can also be called as Bulk's modulus(though this applies even to solids)\nit can also be the coeff of viscosity taken velocity gradient times\nthere can be various other depictions also

If the graph of Volume vs Pressure is a diagonal line with a positive slope, you should be able to conclude that the graph of Pressure vs Volume is also a diagonal line with a positive slope!\n\nSince we know that the gas has expanded, the work done by the gas is positive. Hence, W= corresponding area under Pressure vs Volume graph. If you make a sketch of the graph and indicate the intial and final pressures and volumes of the gas, finding W should not be too much of a problem!

It's good to see people actually thinking about what the terms they're using mean, rather than just plugging them into equations.\n\nBasically, the place where you seem to be confused is here:\n\n"In gas such as water vapour, intermolecular forces of attraction is weak and hence it has low PE"\n\nActually, this means the exact opposite, that the system has very high potential energy. Think about gravity for a minute - if a rock placed at, say, 1 foot above the ground were to fall to Earth, it would not release very much energy. Conversely, if the rock were placed 1 mile above the Earth, it would release a considerable amount of energy. The higher the rock is, the greater it's potential energy. However, the further the rock is away from Earth, the weaker the force of gravity acting on it - thus weak gravitational attraction corresponds to higher potential energy. Similarly with the particles in a gas - if they were to "fall" into a partially bound state such as that of a liquid, they would release energy, and thus the unbound state where the particles are too far away from each other to form bonds is the higher energy state.\n\nThis is not to say that a weaker force always corresponds to a higher energy state - if the reason that the force is weaker is that there is less mass/charge/whatever producing it, that really will lower the potential energy. But in the transition from a liquid to a gas does not change the charge of any of the particles - the reduction in intermolecular forces comes from the fact that the particles are moving out of each other's electrical potential wells, a process which, just like lifting up a rock, raises the potential energy.

solid's particles are compact, while on liquids they are loose but gas' are the most loose (more distances with each other)

actually gas has the highest coefficient of thermal expansion (cte). Liquid has a very low cte by comparison.\n\nWhy gas? Because electrostatic attaction between gas molecules is insignificant. Their collisions are 100% elastic. Liquid molecules have a stable electrostatic attraction between eachother that has to be overcome to allow evaporation. Its this electrostatic attraction that prevents the liquid molecules from flying appart the same way gas molecules do after collisions.

Since butane may be stored in a much lighter, thinner container tan propane, it probably doesn't expand as much.  But at higher elevation, what would the expansion be, more or less?\n\nAlso, if you need to carry the gas and container up a mountain, the lighter container would be better, wouldn't it?

Natural gas is too hard to Compress, so, it is collected straight from the ground and pumped to homes. When a Gas field is found they just use a pipe like they do oil to tap into the Gas pocket. Butane is a gas that can be compressed it liquefies under pressure, that why a Lighter looks like it has Liquid in it, you CAN NOT do this with natural gas. This a easy way to explain it.
