Challenge Problems
Push your limits with challenges.
Question 1
A cylinder contains nitrogen gas at a pressure of 2 atm and a temperature of 300 K. Calculate the volume of the gas in liters if there are 0.5 moles of nitrogen.
💡 Hint: Remember to convert pressure to standard units if needed.
Question 2
If the density of a gas is increased while temperature remains constant, how does that affect the pressure? Provide reasoning.
💡 Hint: Refer to the formula P = nRT/V and consider how n (number density) behaves.
