What is partial pressure

What is partial pressure?


Definition of partial pressure
In a mixture of gases, each gas contributes to the total pressure of the mixture. This contribution is the partial pressure. The partial pressure is the pressure the gas if the gas were in a similar volume and temperature without anyone else.Dalton's law expresses the total pressure of a blend of ideal gases is the sum of the partial pressure of every individual gas.

While the typical symbol for pressure is P or p, partial pressure is demonstrated by an addendum (e.g., P1 or p1).

Partial pressure is important in the fields of chemistry, physics, and biology. Blood levels of oxygen and carbon dioxide are directed by assessing their partial pressure.

Example of partial pressure

Intermolecular forces and we start making a little bit more of a condensed phase such as solids and liquids. you start getting all these unique properties of solids and liquids.  liquids have quite a few unique ones viscosity surface tension and one of the more unique ones is vapor pressure that's a very special case and that's probably another thing completely so let's just think about it if you take water in a container and you allow it to start evaporating the space above the surface of the water will start getting water molecules that means it's a gas now and gases impart pressures so as that builds up what's going to happen is these particles floating above the water can go back into the water unless their whisk away so if you put a lid on the in container all the particles are trapped so the water starts going back into the water phase or I should say the water vapor goes back in as this happens you finally reach a state at which the exiting evaporation rate equals the entering condensation rate and you reach what we call equilibrium so when those two rates equal you establish a constant pressure inside your container that pressure is called the vapor pressure of that liquid in case of water you would say it's the vapor pressure of water it's an example of what we call adynamic equilibrium meaning when you look at the thing you can't tell anything's happening but in actuality there are billions and billions of molecules leaving the surface of the water and there's also billions and billions re-entering and they are exactly the same rate so there's no net change but you have established what we call a vapor pressure.

What happens when you put salt in a lemon ?

  What happens when you put salt in a lemon ? Cut 1 Lemon in 4 Parts And Put Some Salt On It.This Trick Will Change Your Life! Ah, the lovely little lemon. Full of nutrition, this bright yellow citrus kills viruses and bacteria. Its fragrance promotes calm and a feeling of well-being while its oil cleans and disinfects. Lemons help us breathe easier and think and sleep better. What's more, that alkalize our bodies to keep body chemistry in balance.   In every detoxifying drink, lemons clean the liver, fight inflammation, regulate blood pressure, and lower cholesterol. Plus, antioxidants and anti-inflammatories found in lemon attack cancers, relieve pain and boost metabolism.   The fruit is good for hair and skin too, from its astringent properties to carcinoma-killing abilities.Here are a couple uses for lemons you might not have thought of yet.   1) Lemon Salt Kitchen Deodorizer The smell of lemon is distinct. Its essential oil contains limonene, an antioxidant. Inh...

PROPERTIES OF MATTER AND THEIR MEASUREMENT

PROPERTIES OF MATTER & THEIR MEASUREMENT   Properties of matter & their measurement are divided in Physical and chemical properties . Every substance has unique or characteristic  properties. These properties can be classified  into two categories — physical properties ,  such as colour, odour, melting point, boiling point, density, etc., and chemical properties , like composition, combustibility, ractivity with acids and bases, etc.  Physical properties can be measured or observed without changing the identity or the composition of the substance. The measurement or observation of chemical properties requires a chemical change to occur. Measurement of physical properties does not require occurance of a chemical change. The examples of chemical  properties are characteristic reactions of different  substances; these include acidity or basicity,  combustibility, etc. 1)   Mea...

stoichiometry

Introduction to stoichiometry The word ‘ stoichiometry ’ is derived from two Greek words - stoicheion (meaning element) and metron (meaning measure). Stoichiometry is the study of numerical relationship between the amounts of reactants used and amounts of products formed by a chemical reaction. Stoichiometry is based on the law of conservation of mass and the mass of reactants equals the mass of the products. Why do we use this? Stoichiometry problems consist of predicting the amount of gram of product that will form from a reaction.if you know how many grams of reactants you have predicting the number of gram of reactant that will be needed to produce a certain amount of product. How can stoichiometry be used in real life? Let's we start this, stiochiometry can be used in cooking. We going start baking a butter cake, for baking a butter cake needed some ingredient like flour,butter,suger,eggs for bake a nice and tasty butter cake. all this ingredient requi...
