How many kilograms of copper have the same temperature rise as 10 kg water for equal absorbed heat? Copper specific heat $= 0.09 cal / (g^{\circ} C)$ .

Answer:

111.00

Solution:

Equal Q and temperature rise give $m_{C u} C_{C u} = m_{w} C_{w}$ . With $C_{w} = 1 cal / (g^{\circ} C), m_{C u} = \frac{10}{0.09} = 111.11 kg$ .
