Welcome to the General Physics course overview focusing on the fascinating topic of Vapours. In this course, we will delve into the properties and behaviors of vapours, exploring concepts such as unsaturated and saturated vapours, the relationship between saturated vapour pressure (S.V.P) and boiling, methods for determining S.V.P, and the formation of atmospheric phenomena like dew, mist, fog, and rain.

Firstly, it is crucial to differentiate between saturated and unsaturated vapours. Saturated vapours are in equilibrium with their liquid phase, while unsaturated vapours have the potential to hold more substance in vapor form. Understanding this duality is pivotal in comprehending the dynamics of vapours.

Next, we will investigate the intimate connection between saturated vapour pressure and boiling point. Saturated vapour pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature. This pressure plays a pivotal role in determining the boiling point of a substance, a fundamental concept in the study of vapours.

One method we will explore in this course is the determination of saturated vapour pressure using the barometer tube method. This experimental technique allows us to quantify the S.V.P of a substance, providing valuable insights into its vapor phase behavior.

Furthermore, we will examine the formation of atmospheric phenomena such as dew, mist, fog, and rain. These natural occurrences are intricately linked to the behavior of vapours in the atmosphere, showcasing the dynamic interplay between temperature, humidity, and pressure.

As we progress, we will differentiate between dew point, humidity, and relative humidity, essential parameters in characterizing atmospheric moisture. Additionally, we will delve into hygrometry, exploring methods such as wet and dry bulb hygrometers for estimating the humidity of the atmosphere with precision.

In this course, we will engage in practical exercises and numerical problems to solidify our understanding of vapours and their intricate properties. By the end of this course, you will not only grasp the fundamentals of vapour behavior but also gain practical skills in applying theoretical concepts to real-world scenarios. Get ready to embark on a journey into the captivating realm of vapours in the realm of physics.
