Challenge Problems
Push your limits with advanced challenges
A closed container contains 200mL of liquid and 300mL of its vapour at a fixed temperature. If more liquid is added, what happens to vapour pressure?
💡 Hint: Think about how saturation affects the system.
Calculate the effect of increasing temperature on the equilibrium vapour pressure of a liquid with an initial vapour pressure of 50 mmHg at 20°C.
💡 Hint: Remember the relation between temperature, vaporization, and pressure!
