Friday 4/27. An Introduction to Gases. Chapter 13. Kinetic Molecular Theory. Postulate #1 Gases consist of tiny particles (atoms or molecules) Postulate #2

ByT h e C o m b i n e d G a s L a w. Manipulating Variables in equations. Often in an equation we want to isolate some variable, usually the unknown From math: what ever you do to one side of an equation you have to do to the other side Doing this keeps both sides the same

ByA company makes computer chips from square wafers of silicon. It wants to keep the side length of a wafer very close to 17 mm. The area is A ( x ). Find A'(17) . 34 289.

ByGay-Lussac ’s Gas Law. Discovered by Joseph Louis Gay-Lussac in the early 1800's. This law relates to how temperature affects the pressure of a gas when the volume is constant. Temperature vs. Pressure.

ByGas Law Calculations. Boyle’s Law PV = k. Charles’ Law V T. = k. P and V change n, R, T are constant. Ideal Gas Law PV = nRT. T and V change P, n, R are constant. P, V, and T change n and R are constant. Combined Gas Law PV T. = k.

ByGas Laws ch 13 Chem . Section 1 Laws involving changing conditions of a gas. If one condition changes something else does Predict the effect changing pressure or temperature would have on volume of a gas.

ByThe Nature of Gases. Gas Pressure –the force exerted by a gas per unit surface area of an object Due to: a) force of collisions b) number of collisions. The Nature of Gases. The SI unit of pressure is the pascal (Pa) Other units: millimeters of mercury (mm Hg) torr ( torr )

ByThe Behavior of Gases. Properties of Gases The Gas Laws Ideal Gases Gases: Mixtures and Movements. Properties of Gases. Objectives: Explain why gases are easier to compress than solids or liquids are. Describe the three factors that affect gas pressure. Compressibility.

ByEarth Science. Use for Scientific Investigation SOLs SOL 1,2,3 Use Stella for cycles: volcanoes, water cycle, star cycle, rock cycle, other cycles Mapping, GIS tools Agent tools for resource management. Math. Problems with critical skills including basic algebra skills.

ByUnit 5: Gases – Review Session. 11.19 & 20 Ms. Boon Chemistry. Objectives: I can use the gas laws to solve gas law problems and explain the physical properties of gases. Catalyst.

ByPressure. Ingredients : A thermodynamic model of a system, Ω (U,V), which describes the number of microstates of the system when isolated at particular values of U and V, (i.e. in a particular macrostate).

ByCatalyst. Calculators today! 1. What would be the new volume if the pressure on 8 L of gas is increased from 10 atm to 12 atm ? 2. You have 0.2 L of neon at a temperature of 289 K. If you the temperature was initially 350 K, what was the initial volume of the gas?.

ByThermodynamics I. AP Physics. RECAP. Thermal Physics Equations not on the equation sheet c specific heat, units: J/(kg ·K) L Latent Heat, units: J/kg. The Mole. Quantity in Physics mass – quantitative measure of object’s inertia mole – number of particles. Mole & Mass.

ByChapter 14 The Behavior of Gases. Did you hear about the chemist who was reading a book about Helium? He just couldn't put it down. . 14.1 Properties of Gases. OBJECTIVES: Explain why gases are easier to compress than solids or liquids are

ByCh. 5 Gases. Gases are defined by: The particles are free to move (fluid). The particles are far apart. The particles move very fast. The particles have no attraction nor repulsion for each other. The fact that they have no definite shape or volume – they take the shape of the container.

ByChapter 1 Chemical Foundations. CHY 115: General Chemistry I. Chapter Outline. Overview of chemistry Methods of science Measurements Unit systems Quantities measured Taking measurements Accuracy and precision, types of error Significant figures and calculations Dimensional analysis

ByTopic#33: Gas Laws. EQ: How do we calculate the relations between the pressure, temperature, and volume of gases?. Variables:. Volume is measured in Liters, mL, cm 3 , or dm 3

ByUnit 3: Kinetic Molecular Theory and States of Matter. Gases and Their Behavior. Gases and Their Behavior. Gas Pressure and Conversions :. Really . . . Boyles Law:. Thought experiment: sealed syringe full of air. Formula, parameters, real-world understanding. Charles’s Law:.

ByPressure and Temperature. William Thomson “Lord Kelvin”. CA Standards. Measuring Pressure. The first device for measuring atmospheric pressure was developed by Evangelista Torricelli during the 17 th century. The device was called a “barometer”. Baro = weight Meter = measure.
