Practice: A 4.30 L gas has a pressure of 7.0 atm when the temperature is 60.0 ºC. What will be the temperature of the gas mixture if the volume and pressure are decreased to 2.45 L and 403.0 kPa respectively?

The Combined Gas Law is created from “combining” Boyle’s Law, Charles’ Law, and Gay–Lussac’s Law.
Combined Gas Law
Concept #1: The Combined Gas Law
Example #1: A sample of gas initially has a volume of 900 mL at 520 K and 1.85 atm. What is the pressure of the gasif the volume decreases to 330 mL while the temperature increases to 770 K?
Practice: A sealed container with a movable piston contains a gas with a pressure of 1380 torr, a volume of 820 mL and a temperature of 31°C. What would the volume be if the new pressure is now 2.83 atm, while the temperature decreased to 25°C?
