Physics 1IntroductionMechanical properties of metalsQuantity of heatUnitsDifferent systems of unitsDimensional AnalysisMKS/The international system of units (SI)CGS/Gaussian systemFIbS/The British systemThe value of physical quantity must beexpressed in terms of some standard orunits. Units are necessary to comparemeasurements and also to distinguishbetween different quantities.Most physical quantities may be expressed interms of length L, mass M, and time T. The quantities L,M, and T are dimensions. Units can be raised to a power, and so canthe fundamental dimensions.Heat TransferTemperature &ThermometersScreenshot 2022-12-20 130717The heat capacity of a body is the ratio of heatsupplied to the corresponding rise in temperature ofthe body. Heat capacity = Q/TThe specific heat capacity of a material is the quantity of heat required to raise the temperature of a unit mass through one degree. c = Q / mΔTConduction is the process in which heat energy is transferred by adjacent molecular collisions throughout a material medium. The medium itself does not moveConvection is the process by which heat is transferred by the actual mass motion of a Fluid ( free convection-forced convection)Radiation is the process by which heat is transferred by electromagnetic waves.Lower fixed point This is the temperature of puremelting ice, at a pressure of a standardatmosphere.Upper fixed point This is the temperature of drysteam from water boiling at a pressure of onestandard atmosphere.Fundamental interval This is the distance betweenthe fixed points. It is divided into a number of equaldivisions. Each division is one degree.THERMAL EXPANSION Linear ExpansionThermal stressThermal forceArea ExpansionVolume ExpansionOscillationsNonmechanicaloscillationMechanicaloscillationSimple Harmonic OscillationDamped Harmonic OscillationForced Harmonic Oscillation
