a silver ball weighing 50g is removed from a furnace and dropped into a 350g of water at 0°C. if the equilibrium temperature is 10°C and the specific heat capacity of platinum is 230J〖kg〗^(-1)〖°C〗^(-1), what is the temperature of the furnace? neglect the effect of the mass of the calorimeter.

315

anonymous · Answer

can you explain? i really have no idea how to do this. :(

anonymous · Answer

q=mct      so,heat absorbed by water=350*1*10=3500                                              and this(3500) is heat released by silver ball        so, 3500=0.23*50*t           t=314                       
this t is change in temp      so, temp of ball=314=10=315

oops.......t=304    so temp=304+10=314
