You have a block of m = = 100 g of an unknown substance at room temperature (T; = 25°C), and you want to determine what material it is by finding its heat capacity. To do this, you bring out a copper pot (mc 25 g, Ce = 0.385 J/(g°C), T = 15°C) that sits inside an insulating container. Then you put the block in the pot and add mw = 300 g of water (Cw = 4.2 J/(g°C)) at Tw=80°C. After some time, the entire system reached an equilibrium temperature of Tf = 54°C. What is the heat capacity of the unknown material? -
