Answer

Answer:

A. $0.00420\ J/(g\cdot ^{\circ}C)$

Explanation:

Step1: Convert masa a gramos

$m = 10.0\ kg\times1000 = 10000\ g$

Step2: Calcular el cambio de temperatura

$\Delta T=T_{final}-T_{inicial}=70.0^{\circ}C - 10.0^{\circ}C=60.0^{\circ}C$

Step3: Re - organizar la fórmula para $C_p$

$C_p=\frac{q}{m\Delta T}$

Step4: Sustituir valores

$C_p=\frac{2520\ J}{10000\ g\times60.0^{\circ}C}= 0.00420\ J/(g\cdot ^{\circ}C)$
