Question

Calculate Kcal for a calorimeter using thefollowing data: Temperature of hot water bath: 35.5oC Temperature of room temperature water: 23.2oC Final temperature upon mixing 5.0 mL volumes of hot and coldwater: 28.7oC Can someone walk me through this problem. I have a labtomorrow and we have not gone over this material since lastsemester, Promise to rate.

Explanation / Answer

      We Know that :      According to ThermodynamicalRelationship :          Q = m x s x t               The hot water is mixed with the cold water so that the finaltemperature is 28.70C          Q = 5.0 ml x 1 gm / ml x 1 cal / gm 0C x 28.7 0C                =  143.5 Cal.
