Nick Lusskin Chapter 10 – Thermal Physics Outline Thermal Concepts  High temp flows to lower temp  Thermal equilibrium is when temps in two substances in thermal contact are equal T =T +273  Kelvin: K C  Pressure, volume, and temp are all related F  Pressure of a gas is defined as P= A Heat and Internal Energy  Macroscopic: Big picture, Microscopic: Point of view inside system (usually small)  If temp changes, a gain or loss of energy must have occurred  Energy is either rotational or translational kinetic  Molecules have potential energy because of intermolecular forces  Total random kinetic energy possessed by molecules is referred to as the internal energy  Solids have set shape and volume  Liquids have fixed volume but not shape  Gasses have neither fixed shape or volume Specific Heat Capacity  If heating an object with no energy loss, then change it temp depends on 3 things: o Energy supplied o The mass o The substance of the object  The thermal capacity of an object is th energy required to raise an objects temp by 1 K C= Q  Thermal capacity: ∆T Q  Specific heat capacity m ∆T Q=mc∆T Phases [States] of Matter and Latent Heat  Latent heat is the amount of energy associated with a phase change  From solid to liquid is called fusion, liquid to gas is vaporization Q  Specific Latent Heat: M  Change in heat can measured with an electrical apparatus or calorimeter type device The Gas Laws p =c  Pressure Law: T V =c  Charles’ Law: T 1  Boyle’s Law: =cor  pV=c V pV  Equation of state: T =c pV =universal constant (R)  For any type of gas: nT where n=number of moles of the gas  R = 8.314 Joules per mol kg  Ideal gas: a gas that follows all gas laws for p, V, and T and cannot be liquefied 23  Avogadro Constant N =A6.02*10 N  Molar mass n= N A  State for an ideal gas: p=nRT  Derivations: 2 pV= N E ´K o 3 2 o nRT= N EK 3 N N 2 ´ ´ 3 R o n= N so N RT= N3E ∴EK= K 2 N T A A A o R and NAare constants, so T∝E ´K R o The ratio NA is the Boltzmann’s constant B 3 3 R o E K k TB T 2 2 NA Molecular Model of an Ideal Gas  Newton’s laws apply to molecular behavior  No intermolecular forces except for collisions  Molecules are point particles in constant random motion  Pressure of a gas is a result of molecular collisions  Pressure Law: At a constant volume the pressure of a gas is proportional to its temp in K  Charles’s Law: At a constant pressure the volume of gas is proportional to the temp  Boyle’s Law: At a constant temp, the volume of a gas is inversely proportional to its volume
