INTRODUCTION

We are going to explain you about the kinetic molecular theory aplaid to gases. you are going to learn three laws about gases: - Charles law - Boyle-Mariote - Gay-Lussac law

jacques charles

• Born on 12 november 1749, in beaugency
• The scientific Benjamin Franklin visited his country, france , and charles get attract of ficics.
• He decies to study fisics and experimentation.
• He became famous because he invent the aereal glove.

• Born on 12 May 1620, in France
• Was a fisic chemisitry
• Discover the law of gases and makes the law of Mariotte
• Died on May 1689

Edme-MARIOTTE

• Borned on 25 January 1627
• Study on Elton and works with Robert Hooke
• Discover the law of Boyle
• Died on 30 December 1691

ROBERT BOYLE

GAY-LUSSAC

• Born 6 december 1778
• He was a fisic quemestry
• discovorer the fisic properties of gases
• He also discovered the water composition and he works on mixtures of water and alcohol
• Discover the laws of gases

is inversely proportional to the pressure exerted by the gas.

Título 2

Info

• At a fixed temperature, the volume of gas is inversely proportional to the pressure exerted by the gas.
• An example is the syringe

Boyle-mariotte law

+ INFO

LAW OF GAY LUSSAC

• The volume is constant
• If the temperature decreases, the pressure decreases
• If the temperature aument, the pressure aument

• An example of law of Gay lussac is the pressure cooker

Títul

LAW of charles

• The pressure is constant
• If the temperature increases, the volume of the gas increases
• If the temperature decreases, the volume of the gas decreases

+ INFO

Examples

Charles law

A good example is a AEREOSTATIC BALLON

Boyle mariotte

A good example to understand correctly this law is A SHIRINGE

Gay lussac

A good example is a pressure cooker

Formula

Charles's law states that temperature and pressure are directly proportional. This means if temperature increases, then pressure will also increase. On the other hand, if temperature decreases, then pressure will also decrease. The equation for comparing two samples of a gas using this law is V¹/ T¹=V² / T²

Charles law says that the volume is directly proportional to the temperature of the gasWhy?because the molecules the gas moves more quickly and they collide with the walls more quickly so THE PRESSURE INCREASES AND WITH HIM, THE VOLUME Example: AEREOSTATIC BALLONS COULD ELEVATE BECAUSE THE AIR EXPANDS INCREASING ITS VOLUME THANKS OF TEMPERATURE

Formula

When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and therefore the volume is going to be in direct proportion.” The equation of the law is PV = k.

Mathematically, Boyle's law can be written as pV=k, where p is the pressure of the gas, V is the volume of the gas, and k is a constant. An example of Boyle's law in action can be seen in a balloon.

FORMULA

Consectetur adipiscing elit

If we increment the TEMPERATURE, WE ALSO INCRESE THE PRESSURE. Why? Because they are directly proportional and the molecules of the gas are faster. Example: IF WE heat a cooker, and the temperature increases, the pressure and food cooks faster

Boyle's law says that the pressure of a gas in a recipient is INVERSELY PROPORTIONAL TO VOLUME OF THE RECIPIENT ( WHEN TEMPERATURE IS CONSTANT) WHY? because augmenting the volume particles of gas are slower Example: IF WE PRESS THE EMBULUM OR THE BACK OF THE SIRINGE , THE VOLUME OF INSIDE OF THE SIRINGE DISMINUTES.

If you increase the temperature, the pressure will increase too.Why? Because when we increase temperature, molecules move faster Example: WHEN THE PRESSURE COOKER IS HEATED THE PRESSURE AUMENTS SO, THE FOOD IS MADE FASTER
