vapor pressure explained

vapor pressure explained.
understanding vapor pressure. This video explains vapor pressure and boiling. Vapor pressure or vapour pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapor pressure at normal temperatures is often referred to as volatile. The pressure exhibited by vapor present above a liquid surface is known as vapor pressure. As the temperature of a liquid increases, the kinetic energy of its molecules also increases. As the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure.
The vapor pressure of any substance increases non-linearly with temperature according to the Clausius–Clapeyron relation. The atmospheric pressure boiling point of a liquid (also known as the normal boiling point) is the temperature at which the vapor pressure equals the ambient atmospheric pressure. With any incremental increase in that temperature, the vapor pressure becomes sufficient to overcome atmospheric pressure and lift the liquid to form vapor bubbles inside the bulk of the substance. Bubble formation deeper in the liquid requires a higher temperature due to the higher fluid pressure, because fluid pressure increases above the atmospheric pressure as the depth increases. More important at shallow depths is the higher temperature required to start bubble formation. The surface tension of the bubble walls leads to an overpressure in the very small initial bubbles.

The greatest vapour pressure explanation I have ever seen

[manfernal]

this is literally the best explanation of vapour pressure i've ever listened to

[saoudjutt]

You have cleared my query, thanks for such marvelous conceptual videos

[definitely_not_her]

The video is so well made and the explanation is so good, thank you sir.

[_arush]

Nice explajnation sir, you have said to the point words ❤❤❤

[binuv]

Thank you for clearing my long term confusion ❤️

[minutereview]

Best Explanation ever i found in 2 min Thank u very much!

[atthahirahhadijah]

Thanks! I completelwy understand the term now :)

[anomachandrani]

Best explanation thanks sooo much❤️❤️❤️

[vynguyenle]

is the vapor pressure upward or downward sir ? Does vapor pressure mean the pressure exert upward onto the container or the pressure exerted downward onto the liquid surface ?

[pavelivansanchezaldanatecl]

Thank you, I finally get it
Im studying physiology and the book says everytime we breath in we lost water from our respiratory tract due to the atmospheric vapor pressure is less than the v. pressure from our respiratory tract, that explains the dry feeling we get in cold days, the atmospheric pressure decrease even more, lossing more waterdue to the difference in the vapor pressures

[chrisgorden]

nice and succinct, easy to follow. Thank you.

[ShivaniSharma-pdoo]

From this we learned that rate of evaporation increases and pressure decreases

[sonuthakur]

Speak nicely wt is these too slow it's worst
