Talk:Aerosol spray dispenser

Why does an aerosol can become cooler after the gas is released? (Question from 04:12, 19 January 2006 68.251.78.43)

A: It is called adiabatic expansion (I think). --JohJak2 09:04, 19 January 2006 (UTC)[reply]

Boyle's Law. When you compress a gas, it gets warmer. When the gas expands, it gets cooler. When the gas is released from an aerosol can, it expands and cools, thus cooling the can. The same principle is used in air conditioners.--66.162.55.2 20:34, 22 May 2006 (UTC)[reply]

Does anyone know why this entry is linked to Radiological weapons? There doesn't seem to be any connection -- SamuellusSoccus 20:57, 17 February 2006 (UTC)[reply]

I took it out. If someone cares enough we will find out... --JohJak2 20:45, 19 February 2006 (UTC)[reply]

Do aerosol cans always have to be made of metal? Can a transparent material be used, such as plastic? 24 Feb 2006

A: Aerosol containers can be fabricated from glass - mainly used for fragrance products and at low gas pressures. They have also been fabricated using PET, either pigmented or clear. Colin Westley 15:22, 22 April 2006 (UTC)[reply]

If you pierce an aerosol can will the metal in the piercing bend inwards? 17th April 2006

A: Yes it will, but in the interests of safety please don't try it. Colin Westley 15:26, 22 April 2006 (UTC)[reply]

What is the typical pressure inside an aerosol can? Is it true that the cans may rupture at high altitude? What percentage actually ruptures? Any chance of a diagram of the works of a can? Jm546 17:49, 14 October 2006 (UTC)[reply]

Dangers

As a kid, I remember being told about how dangerous it is to spray an aerosol over an open flame, with people saying that the flame would frequently burn backwards faster than the material was moving forwards, drawing the flame into the canister and making it explode. On the other hand, I've just watched a video on YouTube that shows someone doing that very act with no explosions.

Does anyone know if there have ever been aerosol cans that could explode, or was that just an urban legend?

it is very dangerouse... but i admit i have done it once with bug spray and i didnt hurt myself. dont do it, i had a close call, the flame started going bak but i pulled the match away from the can befor anything bad can hapen.
