why LPG filled cylinder does'nt make any sound when shaken?

Answer 1

Should be part liquid, part gas in the volume of the cylinder. The sound it makes is very faint in my experience, but if there is absolutely no sound at all, the liquid is all gone and all that is left is some compressed gas. That is to say, the tank is empty.

Answer 2

LPG does mean Liquefied Petroleum Gas. It is a vapor in it's natural state (or as a byproduct) and has to be compressed (the heat/thermo reaction changes it to a liquid state) into large containers and stored. By the time a consumer gets it in their home use cylinders, the pressure in the propane tank is more or less a vapor or gas again.

Answer 3

Since I and just a poor level one, they won't let me give a thumbs up to Woody and Zorch, but they are both correct, a properly filled LPG cylinder has both gas and liquid and will make a (perhaps faint) sound when shaken.

Answer 4

LPG stands for Liquefied Petroleum Gas. It completely fills the container, so it doesn't make any noise when shaken.

Answer 5

You guys need your hearing checked. Shake it harder, it will slosh.

BTW, LPG containers are never filled completely (80% from memory), there must be allowance for expansion via temperature changes - see the ideal gas law. BOOM, he he

Answer 6

It is filled with compressed gas, so basically when the liquid part of it sloshes around, its automatically displaced with the gas part of it. Might not make much sense, but thats science for ya. Same goes with CO2.

Answer 7

what exactly are you expecting to make noise? it is a container filled with gas molecules. the molecules of the gas are not static enough to produce a sound wave.
