5 kJ
30 kJ
60 kJ
90 kJ
Understanding the Answer
Let's break down why this is correct
The heat capacity tells how much heat the calorimeter takes to rise one degree Celsius. Other options are incorrect because Many students think the temperature rise should be multiplied by the calorimeter’s capacity, giving 67.5 kJ, then they mis‑read that as 30 kJ; Some students assume the heat capacity is per gram, so they divide 67.5 kJ by 2 grams, arriving at 60 kJ.

Definition
Bomb calorimetry is a method used in Chemistry to measure the energy released or absorbed during a combustion reaction. By burning compounds in a bomb calorimeter and analyzing the temperature change, chemists can calculate the energy stored in chemical bonds. This technique is essential for determining the heat of combustion and understanding the energy content of different molecules.
