Answer the following problems 1. A cylinder with a movable piston contains 250 cm3 air at 10°C. If the pressure is kept constant, at what temperature would you expect the volumeto be 150 cm3? 2. A tank (not rigid) contains 2.3 L of helium gas at 25°C. What will be the volume of the tank after heating it and its content to 40°C temperature at constant pressure? 3. At 20°C, the volume of chlorine gas is 15 dm3. Compute for the resulting volume if the temperature is adjusted to 318K provided that the pressure remains the same 4. Oxygen gas inside a 1.5 L gas tank has a pressure of 0.95 atm. Provided that the temperature remains constant, how much pressure is needed to reduce its volume by ½? 5. A scuba diver needs a diving tank in order to provide breathing gas while he is underwater. How much pressure is needed for 6.00 liters of gas at atmospheric pressure to be compressed in a 3.00 liter cylinder ? 6. A sample of fluorine gas occupies a volume of 500 mL at 760 torr. Given that the temperature remains the same, calculate the pressure required to reduce its volume by 1/3.​
