# d Secure Changes and Heat Capacity TabloPart A ough To detormine wheth.docx

d Secure Changes and Heat Capacity TabloPart A ough To detormine whether a shiny gold-colarod rock is actualy gold, a chomistry student decides to measure ks heat capacly She fint the rock and finds that it has a mass of 47 g She then Kinds that, upon absorption of 52 7 J of heat the rock undergoos a rfise in temperature from 25 Cto 57 C. Find the specific heat capacity of the substance comprising the rock Express the specific heat capacity in joules per gram.Celsius to two decimal places. ubrnit Part B This question wi be shown after you complete previous questions) Part C A 55 0-g aluminum block initaly at 275 Cabsorbs 725 J of heat What is the Snal Express your answer in degrees Celsius to one decinal place tempsrature of the auminem? 27201 Wi-Fi Network Name:ATTAq133W Wi-FiPassword:8zxm423hwa8 8 5
Solution
Part A.) Heat absorbed = mcdT
52.7 = 4.7*c*(57 - 25)
specific heat (c) = 0.3504 J/g.C
Specific heat of gold obtained = 0.3504 J/g.C
