The Ideal Gas Law CHEM1901/3 Worksheet 8: The Ideal Gas Law
PV = nRT R is the universal gas constant Critical thinking questions 1 Sketch on the graph below how the volume of a gas changes as the pressure is increased 2 Sketch on the graph below how the volume of a gas changes as the temperature is increased P V
Worksheet 7 - Ideal Gas Law I Ideal Gas Law Ideal Gas Law PV
PV = nRT P = pressure V = volume n= moles of gas, R = universal gas constant T = temperature The value of R varies with the units chosen: R = 0 08206 L atm / mol K R = 8 314 J / mol K In all cases, the temperature must be expressed in K, degrees kelvin 1 To standardize results, chemists often use a set of experimental

PV = nRT The ideal gas law It is an equation of state R = 0 8206 L• atm/mol • K also expressed as 0 8206 L atm mol−1 K−1 Useful only at low Pressures and high temperatures Guaranteed points on the AP Exam These next exercises can all be solved with the ideal gas law, BUT, you can use another if you like Exercise 6 Ideal Gas Law I

SAMPLE EXERCISE 10 2 Using a Manometer to Measure Gas Pressure PV = nRT PV = nRT PV = nRT PV = nRT PV = nRT PV = nRT PV = nRT Ideal-Gas Equation
A Guide to Ideal Gases
PV=nRT 2 1 The gas’s pressure decreases by 25 2 2 The pressure changes to 4P: P = 4P = 2 3 The temperature remains unchanged (at T): T = 1T = Question 3 3 1 Its volume will increase 3 2 As the gas’s temperature increases, the average kinetic energy of the gas molecules increases, so the gas molecules move faster, on average

IDEAL GAS LAW: PV = nRT, where P = pressure of the gas sample V = volume of the gas sample T = Kelvin temperature of the gas sample n = moles of the gas sample R = molar gas constant AVOGADRO'S LAW: At the same temperature and pressure, equal volumes of all gases have the same number of molecules At STP one mole of any gas occupies a
Marked questions are recommended for Revision PART - I
(A) PV = nRT – 2 na V (B) PV = nRT + nbP (C) PV = nRT (D) P = nRT Vb B-6 Compressibility factor for H 2 behaving as real gas is : (A) 1 (B) a 1 RTV §· ¨¸ ©¹ (C) Pb 1 RT ¨¸ (D) RTV (1 a) B-7 At low pressures (For 1 mole), the Vander Waal’s equation is written as 2 a p V ªº «» ¬¼ V = RT The compressibility factor is then equal
