Yes, gases are temperature sensitive. Even car tyre pressures are kept slightly low in summers due to air expansion.hamiclar01 wrote:I disagree. Gases are temperature sensitive. Remember Charles' law, Gay Lusaac's law and Clayperon's ideal gas laws?karizman wrote:
Dear compressed air is not temperature sensitive like CO2 & any change in temperature is not going to change a point of impact.
If the compressed air cylinder conducts heat, the contained gas pressure may vary, so too the point of impact. The degree of variation depends on the gun in question, and is obviously more pronounced when you use it outdoors exposed to the elements than in an indoor range. The famous Steyr LG 100/110 HPs for example, are notorious for changing their zeros in winter.
I read some where that PCP shooters take their guns well in advance before the shooting time so that the gas [co2] is 'temperature tuned' with the surrounding atmospheric temperature in which they have to shoot.
