The heat capacity of our bomb is 840 joules per Celsius. And our specific heat capacity for water is 4.18 joules per Celsius times ground. We want to find the final changes, the energy of our surroundings when 1 mol of glucose is combusted. So let's visualize the example. So here's our bomb kilometer, and we're basically taking the red oxygen molecules and the purple glucose molecules. We're mixing them, combusting them in our bomb or steel bomb.
