Kinetic-Molecular Theory central model that explains microscopic gas behavior at the level of individual particles T In Charle's Law, V is proportional to.... Graham _____'s law is derived from the equation combining Boyle's, Charles's, Gay-Lusaac's, and Avogadro's law. ideal gas constant the proportionality constant that appears in the equation of state fo 1 mole of an ideal gas; R = (0.0821 L x atm)/(molxK) Convert 300K into degrees celcius 27 degrees celsius 24.8L/mol one mole of any gas at SATP occupies.... higher the warmer a gas, the ____ the pressure. Real Gases not ideal, volume determined by their atoms size, attractive and repulsive forces among other molecules atmospheric pressure results from the collisions of atoms and molecules in air with objects. What number do you add to convert degrees celsius to kelvin? 273!! Boyles Law the volume occupied by a gas is inversely related to its pressure crystalline solid a solid whose atoms , ion, or molecules are arranged in an orderly geometric, three dimensional sturcture 0 degrees Celsius and 1 ATM STP (Standard Temperature and Pressure) conditions are.... stay the same if volume increases and temp stays the same, the pressure will vapor pressure the pressure exerted by a vapor over a liquid What does the Charles law state? The volume (V) increases proportionally as the temperature (T) increases normal boiling point point of a liquid at a pressure of 101.3 kpa What is the molar volume of a gas at SATP? 24.8 L/Mol universal gas constant R in the ideal gas law is known as the.... What is the formula for the combined gas law? p1v1 = p2v2------------ T1 T2 The Ideal Gas Law pV = nRT, where R is the universal gas constant P₁V₁ = P₂V₂ Gay-Lussac's Law P/T Charles Law Equation V1/T1=V2/T2 pressure force per unit area 1 101.325 kPa = _______ ATM SATP 25 degrees and 100 KPa volume Coefficients in a balanced chemical equation involving diatomic gases do not indicate ____. millimeters of mercury a unit of pressure force per unit area Pressure is measured as.... diffusion process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated hydrogen bond attraction between hydrogen in one molecule to O, N, Cl, F in another molecule French physicist Jacques Charles determined the relationship between the ______ and ______ of a gas temperature and volume elastic collision collision in which no kinetic energy is lost; kinetic energy can be transferred between colliding particles but the total kinetic energy remains the same. 22.4L/mol one mole of any gas at STP occupies.... masses at same temp and pressure, balloons of equal volume will have equal ____. Grahams Law of Effusion Equation Rate1/Rate2=square root of (M2/M1) melting point the temperature at which a crystalline solid becomes a liquid standard atmosphere is the pressure required to support 760 mm of mercury in a mercury barometer at 25 celsius pascal the SI unit of pressure; one of these is equal to a force of one newton per square meter. partial pressure the pressure of each gas in a mixture gas pressure results from the force exerted by a gas per unit surface area of an object. temperature and the pressure Gay-Lusac's Law ONLY works if the ________________________ remain constant Grahams Law of Effusion rate of effusion is inversely related to the square root of its molar mass amorphous solid a solid in which the particles are not arranged in a regular, repeating pattern what is the formula for molar volume? n= v --- V Graham's law of effusion states that the rate of effusion for a gas is inversly proportional to the square root of its molar mass. increases, decreases, temperature, amount of gas Boyle's Law: as the pressure on a gas ________, the volume of the gas ________ proportionally, provided that the ________ and the _____________________ remain constant. What formula do we use when we need to find the relationship of amount in moles, mass and molar mass? n= m -- M What is the formula used in the Charles Law? V1 = V2-- --T1 = T2
