5.67 grams of metal is heated to 100.00 celscuis and transferred to 10.00 grams of water(cs=4.18j/g.c), intially at 21.0 c, in an insulated calorimeter. the metal cools and teh water warms untill an ewuilibrium temperature of 23.45 c is attained. calculate the specific heat capacity(cs) for the metal, and show your work..identify the metal among the following choices
metal; cs(j/g.c)gold=.129silver=.236nickel=.444titanium=.523
