what is the shape butane?

n-butane\n/\n&#92;\n/\n\ni-butane\n&#92;_\n/\n\nBest I could do here.

yes \n\n CH4, colorless, odorless, gaseous saturated hydrocarbon; the simplest alkane. It is less dense than air, melts at −184°C, and boils at −161.4°C. It is combustible and can form explosive mixtures with air. Methane occurs naturally as the principal component of natural gas; it is formed by the decomposition of plant and animal matter. When this decomposition occurs underwater in swamps and marshes, marsh gas is released. The firedamp of coal mines is chiefly methane

You have not stated where these vapors are coming from or what their purity is, but in general propane vapors can be compressed, cooled and thereby liquified. At approximately 200 psi and 100 degree F. propane can be condensed from a vapor to a liquid. I say approximately, because propane seldom exists in the pure form but is usually mixed with small amounts of methane, ethane and butane.

Oh yeah. Shape is everything. A sphere is the perfect shape for holding pressure. But the reason we dont see many spheres holding pressure is that they are also inconvenient in shape, so we have the next best thing - cylinders. LGP tanks, oxy tanks, scuba cylinders etc. Round sides even out the pressure, thats why you dont see square tanks. Also remember that when they test a tank for how well they hold pressure they fill it with water and pressurise the water, if you did this with just air, it will explode when the pressure gets too high. Thats called a hydraulic pressure test and it is marked on all pressure vessels. There is a test pressure and safe working pressure stamped in to all tanks.

A hydrocarbon where some of the hydrogens have been replaced with alkyl side-chains or other elements (e.g. halogens, oxygen-containing, or nitrogen-containing groups)

Its a mixture of hydrocarbons. It doesn not have a name because it is not composed of one compound.

a variety of hydrocarbon that has linear bond of 6 carbons and 2 nitrogen. The rest of atom is hydrogen. Its chemical formula is C6H16N2 and the structure is   \nCH3-CH2-NH-CH2-CH2-NH-CH2-CH3

T-shaped molecules cannot be from trigonal planar because the only angles possible in a trigonal planar arrangement are 120 degrees, and T-shaped have a 180/90 angle difference.  This is possible for trigonal bipyramidal molecules because you would have two atoms at the axial positions and one equatorial, leaving you with two lonepairs in the other equatorial positions and a 180/90 angle difference between atoms around the central atom.

The spherical shape is the strongest against internal or external pressure.  Next comes a cylindrical shape with spherical end caps.  Next comes a cylindrical shape with indented end caps sort of like the bottom of  a champagne bottle.\n\nThe spherical shape also has the most volume for the surface area so less metal is needed to make the vessel.  \n\nIn other words, you get the strongest vessel using the least amount of material, with a sphere.

Fire is supposed to be a plasma and/or energy. It goes up because the expanded gasses in the flame "weigh" less than cool air (like a hot air baloon). It doesnt have a shape. it adapts to the shape of the container. It looks like a drop because of the hot air "pulling" it up.

well are they charcoal or propane

You get napalm.\n\nIf you google "gasoline and styrofoam", the first thing that pops up is a short explanation from totse.com which has a TON of other articles about things like this.

well, the ideal gas law is PV = mRT.  You need to write this expression for the butane that escaped the lighter, because we don't have enough information about the butane still in the lighter to solve the problem (we don't know the pressure).\n\nFirst you need to convert all your units into the units found in your gas constant, R. looking at the information given, you can see that you'll need the gas constant with units of PV/(mT).\n\nR for an individual gas is the universal gas constant, R_u, divided by the molar mass, which is what we're trying to find. \n\nR = R_u/M\nR_u = 8.314 kPa*m^3/(kmol*K)   [I chose this form because it most closely matched the form I know I need]\n\nThis means that really, the ideal gas law is:\n\nPV = m(R_u)T/M\n\nConversions:\nvolume:  1m^3* = 1000 L\n           477ml = 0.477L = 0.000477 m^3\n-note: you need to know the volume of butane that escaped the lighter.  To do this, find the density of butane (mass/volume) of the origional amount of butatane, and then divide the mass that escaped by the density. You're assuming that the density is constant, because we don't know the volume of butatane that escaped the lighter, or the pressure inside the lighter.  If you have to list sources of error, this would be one.\n\ndensity  = (0.01311 kg/0.000477m^3) = 27.28 kg/m^3\n\nV = 0.00072 kg/27.28 kg/m^3 = 2.6 x 10^-5 m^3\n              (see how the kg units cancel, leaving m^3)\n             \nTemperature:\n23 degrees Celsius  = 23 kelvin\n\nPressure:\n100.33 kPa  - this would be about atmospheric pressure\n\nMass:\n1kg = 1000g\n\n13.11g = 0.01311 kg\n12.39g = 0.01239 kg \n0.72g = 0.00072 kg\n\n\nPutting the numbers in pv  = mrT, with units :\n\n(100.33 kPa)(2.6x10^-5 m^3)=0.00072 kg*(8.314 kPa*m^3/(kmol*K))*(23 K)/M \n\nI would write all that down on a piece of paper, so you can see it more clearly.  The key to getting this kind of problem right is making sure that all your units cancel, leaving you with only the units you want- in this case, kg/kmol.\n\nSolving for M, and canceling all the units, I got:\n\n0.0189 kmol/kg = 1/M\n\nM = 52.9 kg/kmol\n\n\nAccording to my tables, the actual value for Butane is 58.124 kg/kmol, so this is pretty close!\n\n\nHope this helped.  Feel free to email me if you need more help.

take a straw (cylinder) and ram it through a potato.  If you do it right, the straw will go right through the potato!  The cylinder is the strongest and most stable of the shapes and you can see why soups, veggies, fruits, etc. all come in cans!\n\nRight triangels, or right angles are all around you.  The floor and the wall of you room for example.  The bottom of a pool is a good example of an obtuse triangle, suspension bridges - trapezoid, if you look at the tip of a pencil - it's a cone but the shape of a cone when you look at it head on is a scalene triangle
