How to fill a co2 bottle?

Good answer mate, that'd get you an A+ if I was marking it.
Unless it was late in the day when I just give everything a B+, bad kids are happy and the good ones won't complain. He He.

They let him be a Teacher. Good god no.

You're right, cos it's a reaction in the Physics sense

 

[JoseDominguez]

An endothermic reaction is an endothermic reaction, doesn't matter whether it's chemistry or physics.

hmmmm,this is getting geeky

But, it is relative (not in the E=mc2 sense) to energy of the thermal variety, so Physics, is the nature of the beast.LOL

hi ally
next time we train at abridge see me or sheriff we will show you
how to do it safely

Yes, it would be IF THERE WAS ANY REACTION TAKING PLACE AT ALL!!!

If the gas is just going from one place to another then there is no reaction?!

That's what I meant...

The movement of the gas triggers the reaction
The reaction being the transference of heat energy
Why else would the bottle frost up ????

hi mole i was shown last training day so should be able to fill but might need to be reminded

WHAT?! Look up your "ideal gas laws"

The bottle frosts for the reasons already explained - no addition of any other chemical/gas/solid is taking place. The chemical make-up of the contents of your bottle are not changing! That's not a "reaction" - that's a phase change. The gas/liquid is "doing work", therefore energy used must be replaced - ie, heat is absorbed from the surroundings. Simply moving stuff around does not make a reaction.
