8. Since pressure and temperature are directly proportional, their ratio gives a constant number (provided that volume and number of molecules are kept the same). So P1T1=a constant = P2/T2. It doesn't really matter what the constant is. As long as volume and the number of molecules remains constant: P1/T1 = P2/T2. This is only true when a Kelvin temperature scale is used. This is not true in the Celsius scale (or any other temperature scale). %3D If a sample of gas occupying some volume has a pressure of 1.53 atm at 298 K, what is the pressure at 310. K? 9. If a sample of gas occupying some volume has a pressure of 1.5 atm at 25 °C, what is the pressure at 50. °C?
