QuestionHow much energy is needed to heat $10 \mathrm{~g}$ of iron vs. aluminum by $1{ }^{\circ} \mathrm{C}$?
$$\mathrm{C}_{\mathrm{Fe}}=0.450 \frac{\mathrm{J}}{\mathrm{g} \cdot{ }^{\circ} \mathrm{C}} \quad \mathrm{C}_{\mathrm{Al}}=0.900 \frac{\mathrm{J}}{\mathrm{g} \cdot{ }^{\circ} \mathrm{C}}$$
A. Fe needs twice as much energy as Al B. Fe needs half as much energy as Al C. Fe needs 0.450 times less energy than Al D. Fe needs 0.450 times more energy than Al
