Question

Hi, can someone check if I did the chart right? and also the work thanks.

Use the table below to identify the type of metal in the Spede et Water quid Vane Iron Cooper Aluminum 0.09 O.RS Lead 0.214 0.17 Unknown metal Mass of metal ) 29.5g Initial temperature of metalo 180.

Answer 1

Mass of water, m= 125g Specific heat capacity of water, s = 4.184J/g °C temperature change of water, AT = 23.43°C -20.00 °C = 3.43 °C Heat gained by water qwaer = mxsXAT = 125gx(4.184J/g °C)(3.43 °C) = 1794 Heat lost by metal, 9 metal =-water =-1794) Heat lost by metal 9 metal = m metal X Smetal ATmeial AT metal = 23.43°C-180°C =-156.57 °C Smetal = _ I metal Mmetal AT metal -1794) 29.5g(-156.57°C) =0.3884J/g °C = 0.388J/g °C From the table identity of metal = zinc
