1PHYSICS SUMS ASSIGNMENT1. SubstanceMass (in kg)SHC (J/kgºC)InitialTemperature (inCelsius)FinalTemperature =26Copper0.0940018dT=8Cold Water0.1418018dT=8Brass0.15? (suppose C)95dT=69Hence, =) heat gained by copper + heat gained by cold water = heat lost by brass=) 0.09*400*8 + 0.1*4180*8 = 0.15*C*69=) 288+3344=10.35C=) 3632=10.35C=) C=350.917=) C=350.92Answer SHC of brass is 350.92 Jkg-1ºC-12.

2PHYSICS SUMS ASSIGNMENTHeat gained by ice= heat lost by copper + heat lost by water=) 0.023*C*6=0.075*400*18+0.1*4180*18=) 0.138C=540+7524=) 0.138C=8064=) C=58434.78Answer Specific Latent Heat of fusion of ice is 58.43 Kilo Joule3. a.SolidLiquidGasesretains a fixed volume andshape rigid - particles locked intoplaceassumes the shape of the partof the container which itoccupies particles can move/slide pastone anotherassumes the shape and volumeof its container particles can move past oneanothernot easily compressible little free space betweenparticlesnot easily compressible little free space betweenparticlescompressible lots of free space betweenparticlesdoes not flow easily rigid - particles cannotmove/slide past one anotherflows easily particles can move/slide pastone anotherflows easily particles can move past oneanotherb. The ice cube would consume the heat from the atmosphere and the molecular forces binding theice cube in the solid structure would be decreased causing the ice to melt in liquid state.
