Question

calculate the amount of heat required to convert 200g of ice at
-10°C into water at 10°C

Vara · Accepted Answer

Heat required to convert ice at -10oC to ice at 0oC:Q1=mc△t
=200×0 5×10 =1000 calHeat required to convert ice at
0oC to water at 0oC:Q2=mL =200×80 =1600 calHeat required to
convert water at 0oC to water at 10oC:Q3=mc△t
=200×1×10 =2000 calTotal heat required to convert ice
at -10oC to water at 10oC:Q=Q1+Q2+Q3 =4600 cal
