A bag of ice was placed on a patient’s head. The ice bag contained 220.0g of ice at 0.00°C. When the ice bag was removed, all of the ice inside had melted and the liquid had a temperature of 21.00°C. How many joules of heat were added? [92.59 kJ]

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
