Question

Are vapour pressure and saturation pressure the same?

Answer 1

Hint : When a liquid is placed in a vessel that is constantly heated, the molecules of the liquid may be observed flowing in various directions at different rates. This is owing to the fact that the molecules in the liquid have varying kinetic energy. When a liquid is heated, the energy of the molecules rises, the molecules become lighter, and they occupy the liquid's surface. Evaporation is the term for this process. The molecules visible on the liquid surface are referred to as vapour.

Complete Step By Step Answer:
Vapour pressure, also known as vapour equilibrium pressure, is the pressure exerted by a vapour with its condensed phases (solid or liquid) in a closed system at a certain temperature (in a system with thermodynamic equilibrium). The equilibrium vapour pressure is a well-known indication of a liquid's evaporation rate. Particles' proclivity to escape from a liquid (or a solid) is known to be linked. The term "volatile material" refers to a substance that has a high vapour pressure at room temperature. It should be emphasised that vapour pressure refers to the pressure exerted by a vapour above a liquid surface.
Saturation pressure is the pressure at which a given liquid and its vapour, or a given solid and its vapour, may coexist in equilibrium at a given temperature. The saturation pressure of a pure material is solely determined by its temperature. With increasing temperature, the saturation pressure rises. At 100 degrees Celsius, liquid water has a saturation pressure of 101.3 kPa, but at 5 degrees Celsius, it has a saturated pressure of 0.8721 kPa. Tables, charts, and other visual representations of saturation pressure and temperature data for a variety of widely used refrigerants are available.
The difference between vapour pressure and saturation pressure is insignificant. The temperature at which liquids begin to boil at a given temperature is known as saturation pressure. The propensity of a liquid to turn into a vapour is measured by its vapour pressure. At a particular temperature, it is the pressure imposed by a vapour in thermodynamic equilibrium on its condensed phase.

Note :
The difference in pressure between vapour and saturation is negligible. Saturation pressure is the temperature at which liquids begin to boil at a given temperature. Vapour pressure is a measurement of a liquid's proclivity to convert into a vapour. It is the pressure imposed on a condensed phase by a vapour in thermodynamic equilibrium at a certain temperature.
