When the gas spring is compressed, how does apply the equation Pressure x volume / temperature = pressure x volume / temperature ?

Does the temperature change with the volume reduction or it remains constant? If this statement is true, the equation could be simplified to P1*V1 = P2*V2.

Can somebody confirm?

Jacques Beaudoin

The changes in volume are normally not rapid enough to change the temperature markedly and anyway the gas will return to ambient temperature. The relative size and volume of the rod and chamber will alter the characteristics of the spring. If there is a vast amount of volume and a small rod the power of the spring will not alter much and vice versa. You can therefore design your spring from an Excel spreadsheet or similar. —Preceding unsigned comment added by 86.3.250.35 (talk) 11:49, 1 May 2008 (UTC)
