Use the gas laws to explain the following phenomenon?

Question

I know that tire pressure increases on a hot day because rise in temperature is related to rise in temp, but can you explain the following phenomenon? Please use charles's, avogado's, boyle's or the ideal gas law to illuminate
1. The "popping" sound of a paper bag
2. Weather ballon expansion as it ascends.
3. The noise of a lightbult going out.

Answer 1

1) Popping sound of a paper bag. This is caused by the violent expansion of gas due to increase of pressure, so here we apply Boyle Law (P1V1 = P2V2).

2) Weather ballon expansion as it ascendes. When heated gas (higher temperature) is inhaled by the ballon the volume increases. Here we apply Charles's Law (V1/T1 = V2/T2).

If ballon is not feed with heated gas, then volumen increases due to decrease in external pressure that causes increase of internal pressure of ballon. So, here we apply Boyle's Law.


3) The noise of a lightbulb going out is due to sudden heating of gas inside of bulb (when little resistor makes shortcircuit for example). So pressure increases, breaking the glass.
We apply the Gay-Lussac Law (P1/T1 = P2/T2)

Good luck!

Answer 2

Astromony was fairly advanced during that time and much of that knowledge was lost because of the dark ages and war. The Quran, much like the Bible and the Jewish religious works are general knowledge pieces. You can read about a space craft in an Encyclopedia, but it doesn't tell you exactly how it works, how it's made or how to fly it. These works work the same way and should be considered starting pieces for further knowledge rather than ending pieces (like the whole evolution debate in te United States).

Answer 3

2. Weather baloon--Boyle's law P1V1 = P2V2
As you go higher the atmospheric pressure decreases thus causing an increase in volume.
As for the others not sure..is the popping sound when you open the bag fast or when you slam a closed bag?
