Practice Questions
Question 1
A gas sample has a volume of 4.0 L at 2.0 atm and 300 K. If the volume is expanded to 8.0 L and the temperature is increased to 600 K, what is the new pressure?
Question 2
A gas sample contains 0.75 moles at 400 K and occupies 5.0 L. What is the pressure of the gas? (Use $R = 0.0821\,\text{L·atm/(mol·K)}$)
Question 3
A gas at 3.0 atm and 2.0 L is expanded to 6.0 L at constant temperature. What is the final pressure?
Question 4
A gas sample is cooled from 600 K to 300 K at constant volume. If the initial pressure was 4.0 atm, what is the final pressure?
Question 5
A gas sample has a volume of 12.0 L at 500 K and 1.5 atm. If the temperature is lowered to 250 K at constant pressure, what is the new volume?
