For many purposes we can treat propane (C3H₂) as an ideal gas at temperatures above its boiling point of -42. °C. Suppose the temperature of a sample of propane gas is lowered from 24.0 °C to -12.0 °C, and at the same time the pressure is changed. If the initial pressur was 0.62 kPa and the volume increased by 40.0%, what is the final pressure? Round your answer to 2 significant digits. kPa

The combined gas law states that for a fixed amount of gas, the quantity PVIT is constant. This is often expressed by the equation P¡V PV2 T2 where P is the pressure, V is the volume, and T is the temperature, and the subscripts 1 and 2 denote two different conditions. Rearrange the combined gas law to solve for Pj. P = A gas with an initial temperature of 271 K and initial volume of 15.0 L is heated to 317 K and compressed to 10.2 L. The final pressure of the gas is 4.28 atm. What was the initial pressure (P¡) of the gas? P1 = atm
