Answer

(a) $1.30\times 10^3J$, it is 1.29 times more than the specific heat. (b) $4.19\times 10^6J$, it is 1000 times more than the specific heat.

Work Step by Step

(a) We know that $Q=mC\Delta T$ $\implies Q=\rho V C\Delta T$ (where $m=\rho V$) We plug in the known values to obtain: $Q=(1.29Kg/m^3)(1.00m^3)[1004J/(Kg.K)](1.00^{\circ}C)$ $Q=1.30\times 10^3J$ Thus, it is 1.29 times more than the specific heat. (b) We know that $Q=mC\Delta T$ $\implies Q=\rho V C\Delta T$ (where $m=\rho V$) We plug in the known values to obtain: $Q=(1000Kg/m^3)(1.00m^3)[4186J/(Kg.K)](1.00^{\circ}C)$ $Q=4.19\times 10^6J$ Thus, it is 1000 times more than the specific heat.
