Heat Capacity of a Calorimeter, Question 4A.11

Postby Sam Joslyn 1G » Mon Jan 28, 2019 8:28 pm

Question 4A.11 (7th edition) asks for the heat capacity of a calorimeter given the information that 22.5 kJ of energy increases the calorimeters water bath from 22.45 degrees C to 23.97 degrees. since the formula for a calorimeter's heat capacity is Ccal=-q*(delta)T, why is the answer a positive value and not a negative one?

Because the 22.5 kJ of heat is supplied to the system, it is actually calculated as a negative number, so the solution will turn out positive. Hope that helps!
