Plz explain this ... u calories of heat are absorbed by the system. the molar volumes of ice and ualer

U Calories of heat are absorbed by the system. The molar volumes of ice and Ualer are 0-0196 and 0-0180 litre respectively. Calculate AH and AE. Solution: Since AH = p bx. 5. When 1 mole of ice melts at 0°C and at constant pressure of 1 atm, heat absorbed by the system at constant pressure = 1440 calories. In the equ uation AH = AU + pAV pAV=76x 13.6 x 981 (18-19.6) ergs 76x 13-6 x 981 x 1-6 4-18 x 10 pAV is very small compared to AU, pAV can be neglected. calories p-1 atm 76 x 13-6 x 981 dynes, hus, AH= AU 1440 calories. =-0-039 calories.
