Introduction
In this experiment, we will be determining which kind of wood gives out more heat because we have seen wood customers asking for wood that burns the best.
Aim
To determine what wood gives off more heat which could be helpful in knowing the wood that burns the best.
Theory
Calorimetry is the science performed with an instrument called the calorimeter for measuring the change in the state of matter for the purpose of measuring the heat change associated with the change in the state of matter.
Requirements
1. Calorimetry,
2. Olivewood,
3. Almond wood,
4. Junk wood (it is a low-density wood such as cottonwood),
5. 14 litres of water,
Procedure
Step 1: Use the idea of calorimetry to compare the heat energy of three kinds of wood: junk, almond, and olive.
Step 2: Using the gravel displacement, take out six pieces of each wood of the same volume.
Step 3: Under the same condition, burn all the woods.
Step 4: Take 14 litres of water and measure its temperature.
Step 5: Put this water on fire.
Step 6: Measured the temperature of each water after every 15 minutes.
Observation
1. We observed that the olive wood immediately reached the boiling point. Therefore, I had to start with another pot of water.
2. Before calculating the heat, we added the temperature change of the two pots.
3. We found that the junk wood and almond wood had similar temperature changes.
Result
The result of this experiment is that olive wood gives out more heat energy than junk wood and almond wood.
Conclusion
In this experiment, we have used calorimetry to determine which kind of wood burns the best and gives off more heat.
