1. The volume of a gas with a pressure of 1.2 atm increases from 1.0 L to 4.0 L. What is the final pressure of the gas, assuming constant temperature?2. The gas with an initial volume of 24.0 L at a pressure of 565 mmHg is compressed until the volume is 16.0 L. What is the final pressure of the gas, assuming the temperature does not change?
A cylinder containing 20.0 L of compressed nitrogen is connected to an empty (evacuated) vessel with an unknown volume. The gas pressure in the cylinder starts at 25 atm and drops to 2 atm without a change in temperature. Determine the volume of the vessel. the answer is 230 but i dont know how
