The Heat Equation
The heat equation is used to determine the heat gained or lost during a reaction.
Procedures
Step 1: Identify your system and your surroundings. The system is what you are working with in the equation.
Step 2: Give values to the variables.
Step 3: Solve for x
Example 1
500 g of water is in a calorimeter. An endothermic reaction takes place. After the reaction, the temperature of the water in the calorimeter dropped from 34 degC to 24 degC. How much energy did the reaction take in?
Step 1:
Water=system
Reaction=surrounding
Step 2:
deltaH (change in energy) x (In this case deltaH will turn out to be negative, because our system is losing energy.)
