The real reason why gas doesn't like cold weather is because gas is pressurized while its cold. That means in the gas is cold in the can. When this cold gas is released in room temperature, it expands very rapidly because the electrons get excited when met by this air, thus pushing anything out of its way (such as a bb, or a slide). Back to the the point, gas doesnt work good in cold weather because there isn't much contrast between the temperature of the gas and the surrounding air, thus, the electrons are less excited, thus, less rapid expansion of the gas, thus, less power.

Right.
It's been a month since the last post on this topic, yet you felt the need to revive it to give us a basic science lesson?

Yeah, basic and wrong. Learn gas dynamics before commenting on a thread like this.

Gay-Lussac's law. The temperature of gas is directly proportional to it's pressure. So, a lower temperature = a lower pressure. And of course a lower pressure = weaker shots from your GBB.
P1/t1=P2/t2
A gas cylinder containing explosive hydrogen gas has a pressure of 50 atm at a temperature of 300 K. The cylinder can withstand a pressure of 500 atm before it bursts, causing a building-flattening explosion. What is the maximum temperature the cylinder can withstand before bursting?
Let's rewrite this, identifying the variables:
A gas cylinder containing explosive hydrogen gas has a pressure of 50 atm (P1) at a temperature of 300 K (T1). The cylinder can withstand a pressure of 500 atm (P2) before it bursts, causing a building-flattening explosion. What is the maximum temperature the cylinder can withstand before bursting?
Plugging in the known variables into the following mathematical expression
P1 / T1 = P2 / T2
50 atm / 300 K = 500 atm / T2
50 atm ( T2) = (500 atm) (300 K)
T2 = (500 atm) (300 K) / 50 atm = 3000 K
we find the answer to be 3000 K.

Gas in relation to airsoft is pretty easy to explain:
More heat = more pressure = more power.
Less heat = less pressure = less power.
That's all you *really* had to say. I still would have hollered at you for bringing the post back from the dead though.

I guess that was what i was trying to get at... I run off of total visual memory so some times i do get the facts distorted... thanks for clearing that up xaos.
