When a 140g piece of metal at 70 degrees C is
placed in 220g of water at 0 degrees C, the metal
is cooled, and the water is warmed and
both come to a final temperature of 10=C.
What is the specific heat of the metal?

Best ResponseYou've already chosen the best response.0The heat exchanged between the metal and the water is the same (assuming that this is a closed system (which it isn't by the way)). Therefore: \[C _{water}*m _{water}*\Delta T_{water} = C_{metal}*m_{metal}*\Delta T_{metal}\] \[C_{metal} = C_{water}m_{water}\Delta T_{water}/(m_{metal}\Delta T_{metal}) = 1.16 KJ/kgK\] for example sand has similar specific heat.
