A metal pellet with mass 100.0 g, originally at 88.4 °C, is dropped into 125 g of water originally at 25.1 °C. The final temperature of both the pellet and the water is 31.3 °C. Calculate the heat capacity C (in J/°C) and specific heat capacity Cs (in J/g°C) of the pellet. The specific heat of water is 4.184 J/g°C.
