The volume of gas is 5.0 L when the temperature is 5 C. If the temperature is increased to 10 C without changing the pressure, what is the new volume? a) 2.5L b) 4.8 L c) 5.1 L d) 10.0 L 2. 2.80 L of a gas at 2.58 atm is compressed to a volume of 1.20 L. What is the pressure if the temperature is held constant? 3. If you have a container with CO2 and H20 gases, which gas would effuse faster and how many times faster would it effuse?
