14. If two substances of equal mass are supplied the same amount of thermal energy and their final temperatures are different, you can assume that they have d. different densities a. different heat capacities b. the same volume e. different volumes c. different abilities to conduct heat 5. How much heat is required to raise the temperature of \( 40 \mathrm{~g} \) of water \( 20^{\circ} \mathrm{C} \) ? \( \left(\mathrm{C}_{\mathrm{w}}=4.18 \times 10^{3} \mathrm{~J} / \mathrm{kg} \cdot{ }^{\circ} \mathrm{C}\right) \) a. \( 5.2 \mathrm{~J} \) d. \( 3.3 \times 10^{3} \mathrm{~J} \) b. \( 3.3 \times 10^{-1} \mathrm{~J} \) c. \( 2.1 \times 10^{2} \mathrm{~J} \) c. \( 8.0 \times 10^{-1} \mathrm{~J} \)
