(Solved): At 1 bar, how much energy is required to heat \( 63.0 \mathrm{~g} \mathrm{H}_{2} \mathrm{O}(\mathrm ...
At 1 bar, how much energy is required to heat \( 63.0 \mathrm{~g} \mathrm{H}_{2} \mathrm{O}(\mathrm{s}) \) at \( -18.0^{\circ} \mathrm{C} \) to \( \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \) at \( 173.0^{\circ} \mathrm{C} \) ? Use the heat transfer constants found in this table. Step 2: How much energy is needed to melt \( 63.0 \mathrm{~g} \mathrm{of} \mathrm{H}_{2} \mathrm{O}(\mathrm{s}) \) ? The heat of fusion for water is \( 333.6 \mathrm{~J} / \mathrm{g} \).

Use the heat transfer constants found in this table. Step 3: How much energy is needed to heat \( 63.0 \mathrm{~g} \mathrm{H}_{2} \mathrm{O}(\mathrm{I}) \) from \( 0.0^{\circ} \mathrm{C} \) to \( 100.0 \) " \( \mathrm{C} \) ? The specific heat of \( \mathrm{H}_{2} \mathrm{O}(1) \) is \( 4.184 \mathrm{~J} /(\mathrm{g} \cdot \mathrm{K}) \).

Use the heat transfer constants found in this tablc. Step 5: How much energy is needed to heat \( 63.0 \mathrm{~g} \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \) from \( 100.0^{\circ} \mathrm{C} \) to \( 173.0^{\circ} \mathrm{C} \) ? The specific heat of \( \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \) is \( 2.000 \mathrm{~J} /(\mathrm{g} \cdot \mathrm{K}) \)
