a 20.94 sample of metal is heated to 99.4 *C in a hot water bath until thermal equilibrium is reached.the metalsample is quickly transferred to 100 mL of water at 22 *C contained in the calorimeter. the thermal equilibrium temperature of the metal sample plus water mixture is 24.6 *C. what is the specific heat of the metal?
