For a fixed amount of gas at a fixed temperature, what will happen if the volume is doubled? The pressure exerted by the gas will remain unchanged. The pressure exerted by the gas will halve. The pressure exerted by the gas will double. The pressure exerted by the gas will quadruple. Which of the gases would have the fastest rate of diffusion, assuming all of the gases are at the same temperature? krypton argon helium O neon

A sample of gas has a volume of 540 mL at a pressure of 3.70 atm. The gas is compressed and now has a pressure of 7.49 atm. Predict whether the new volume is greater or less than the initial volume, and calculate the new volume. Assume temperature is constant and no gas escaped from the container.

Using Boyle’s Law, predict what will happen to the pressure of a gas in a container at constant temperature, if the volume of the container is changed to one-half its original size. Nothing will happen to the pressure. The pressure will be decrease to one-half its original value. The pressure will increase to twice its original value. More information is needed.
