The volume of gas in a gas shock absorber varies inversely with the pressure and directly with the temperature. The volume is 24 cu. cm when the temperature is 30°C and the pressure is 25kg. What is the volume when the temperature is 20°C, and the pressure is 40 kg?

Answer 1

first, pressure is in kPa or mg Hg, not kg.
V = kT/P
so
PV/T = k is constant
You want V such that
40V/(20+273) = 25*34/(30+273)
