$15 \, J/^{\circ}C, 600 \, J/kg \cdot ^{\circ}C$

(A) Given: Mass $m = 25 \, g = 0.025 \, kg$,Heat $Q = 300 \, J$,Change in temperature $\Delta T = 45^{\circ}C - 25^{\circ}C = 20^{\circ}C$.Heat capacity $(C)$ is defined as $C = \frac{Q}{\Delta T} = \frac{300}{20} = 15 \, J/^{\circ}C$.Specific heat capacity $(c)$ is defined as $c = \frac{C}{m} = \frac{15}{0.025} = 600 \, J/kg \cdot ^{\circ}C$.Therefore,the heat capacity is $15 \, J/^{\circ}C$ and the specific heat capacity is $600 \, J/kg \cdot ^{\circ}C$.
