Phys 104Exam # 3 Study Guide Lectures: 14-20Lecture 13 (October 13)- Does gravity have external forces?o No external forces = no worko Total energy must remain constant- When the ball rises, the kinetic energy decreases, and the total energy?o stays the same- Gravitational Potential Energy increases when KE?o decreaseso Increases when kinetic energy decreases - W = ?o -deltaULecture 14 (October 15)- The potential energy of the ball-Earth system is proportional to?o the ball’s vertical position- Chemical Bonds are?o The attraction between two opposite electric charges is similar to the attraction of two massesLecture 15 (October 20)- Thermal energy equation?o Eth = Umicro + Kmicro- Range of K temperature?o 0 to 373- First Law of Thermodynamics?o Energy can be transferred between the system and environment through a thermal interactiono W + Q = Delta E- Specific heat equation?o c=Q/(M * deltaT)- Ideal Gas Law?o pV= nRT- Zeroth Law of Thermodynamics?o Two systems placed will transfer thermal energy from hot to cold until equilibriumLecture 16 (October 22)- One mole of any substance contains?o 6*10^23 mol^-1- K = ?o ½ mv2- Adiabatic processes are?o When heat is not transferred- Second Law of Thermodynamics: entropy does what?o Entropy never decreases- Entropy equation?o S = k * ln WLecture 17 (October 27)- The velocity of an object is a __ quantity?o Vector - Velocity points in the same direction as the __ of the object.o Displacement - The kinetic energy of an atom is a __ quantity o Scalar- Kinetic energy is proportional to the __ of the atom.o Square speed- The average velocity of each atom in the gas is?o Zero - Root mean square speed equation?o - Mean free path equation?oLecture 18 (October 29)- RMS displacement equation?o- Fick’s law of particle diffusion?o- Osmotic pressure equation?oLecture 19 (November 3)- Heat transfer equation?o - Heat of fusion is?o Between solid and liquid- Heat of vaporization is?o Between liquid and gasLecture 20 (November 5)- Evaporation is?o Liquid to gas phase- Thermal energy
