1. A gaseous air‑fuel mixture in a sealed car engine cylinder has an initial volume of  600.mL at  1.0atm. To prepare for ignition of the fuel, a piston moves within the cylinder, reducing the volume of the air‑fuel mixture to  50.mL at constant temperature. Assuming ideal behavior, what is the new pressure of the air‑fuel mixture?

2. At  10.°C,  20.g of oxygen gas exerts a pressure of  2.1atm in a rigid,  7.0L cylinder. Assuming ideal behavior, if the temperature of the gas was raised to  40.°C, which statement indicates the new pressure and explains why?

3. Two sealed, rigid  5.0L containers each contain a gas at the same temperature but at a different pressure, as shown above. Also shown are the results of transferring the entire contents of container 1 to container 2. No gases escape during the transfer. Assuming ideal behavior, which statement is correct regarding the total pressure of the gases after they are combined?
