Please answer example 8 - 836000 Q - 0.5 336000 Q - 168000 J - 168000 Amount Of heat Example 8 Calculate the amount Of heat required to melt 100 g ice at —10 oc and form water at 10 oc. Solution Part I: Change of temperature Ice at -10 oc changes to ice at O oc. m 100 g— 0.1 kg

Dear Student ,

Heat required to convert ice at - 10^{o} C to ice at 0^{o} C : Q_{1} = mc △ t = 100 \times 0.5 \times 10 = 500 cal Heat required to convert ice at 0^{o} C to water at 0^{o} C : Q_{2} = mL = 100 \times 80 = 800 cal Heat required to convert water at 0^{o} C to water at 10^{o} C : Q_{3} = mc △ t = 100 \times 1 \times 10 = 1000 cal Total heat required to convert ice at - 10^{o} C to water at 10^{o} C : Q = Q_{1} + Q_{2} + Q_{3} = 2300 cal
