So am i to understand that if you were able to contain fire in a container that it would have absolutely no weight (even fractions of ounces) or that wind doesnt start somewhere or have an ending point. If I exhale, causing wind to move, it eventually stops, correct? What about wind on a greater scale then? I'm lost in my own mind

Both are unanswerable questions. Fire does not weigh anything. It is just really hot air (a plasma), caused by the combustion of molecules.

Wind does not start or end. It's caused by uneven heating of the Earth's surface. This causes the warmer air and the colder air to move, according to gas laws.

I do not think that fire can weight anything.

Wind is air moving horizontally. It's the result of air movement over the Earth. Air moves because of pressure systems - it travels from areas of high pressure to areas of low pressure. The two reasons these pressures change around the earth are:
1. Earth Moves: As Earth moves, it drags the atmosphere around with it, which causes the air to mix with the higher level atmosphere. This creates turbulence and pressure systems.
2. The Sun's Heat: The air around Earth changes temperature all over, depending on the time of day. As the air warms up, it rises. In polar regions where the sunlight spreads over a greater area, the result is less warm air. This means the air over the poles is denser than the air over the equator.

As air rises, low pressure areas are created below. Air in high pressure areas then rushes to fill in the gap. If there's a big difference between the pressure, the flow of air between the two points will be stronger.

Therefore, wind doesn't have any start point or end point.

Fire is actually an effect of combustion and has no weight, although some particles may be combusting within flame. Wind-well the dynamic current of the worlds oceans, which are strongly effected by the earths spin and the moons gravity is the beginning of most wind, which dies when physically stopped by other bodies of air. Of course, secondary winds occur in this process, and the earths spin and the moons gravity cause friction and displacement.

"Fire''' is the light given off by an exothermic chemical reaction. As "light" is only energy it has no weight.

Wind does not start or end. It is the continuous movement of air from places of high pressure to places of low pressure. The relative difference of the high and low and how far they are apart determines the strength (speed) od the wind.

In the northern hemisphere wind circulates clockwise out of a high pressure cell and anti )counter) clockwise into a low pressure cell. This is the opposite in the southern hemisphere.

x^2 + 4x - 32 = 0 component of -32: -4 and eight 4 and -8 -2 and sixteen 2 and -sixteen -a million and 32 a million and -32 decide for component which the result's 4 if u upload them. occasion: -4 and eight = -4 + 8 = 4 (surprising) 4 and -8 = 4 + -8 = -4 (incorrect) -2 and sixteen = -2 + sixteen = 14 (incorrect) 2 and -sixteen = 2 + -sixteen = -14 (incorrect) -a million and 32 = -a million+32 = 31 (incorrect) a million and -32 = a million + (-32) = -31 (incorrect) so, (x - 4 ) (x + 8) = 0 x = 4 or x = -8
