### Saturated and Unsaturated Vapour Pressure

Saturated and Unsaturated Vapour Pressure What is a saturated solution? If in a water sugar solution, the amount of dissolved sugar is equal to the maximum amount that a given amount of water can dissolve at a certain temperature, then that solution is called a saturated solution. What is an unsaturated solution? If in a water sugar solution, the amount of dissolved sugar is less than that amount that a given amount of water can dissolve at a certain temperature, then that solution is called a saturated solution. What is saturated vapour? At a certain temperature in an enclosed space, if the amount of vapour present is equal to the maximum vapour capacity of that space, then that vapour is called saturated vapour. What is unsaturated vapour? At a certain temperature in an enclosed space, if the amount of vapour present is less than the maximum vapour capacity of that space, then that vapour is called unsaturated vapour. What is vapour pressure? Vapour enclosed in a container behaves
