Energy content of the biomass is determined by using

Options

A. bomb calorimeter
B. hygrometer
C. barometer
D. auxanometer

Answer

To determine the energy content of biomass, we follow these steps:

1. **Understanding Biomass**: Biomass refers to the organic material that comes from plants and animals. It is a source of energy that can be measured in terms of caloric content.

2. **Identifying the Measurement Tool**: To measure the energy content of biomass, we need a specific instrument that can accurately assess the caloric value.

3. **Evaluating the Options**:
- **Option A: Bomb Calorimeter**: This is a device used to measure the heat of combustion of a substance. It is specifically designed to determine the energy content of materials.
- **Option B: Hygrometer**: This instrument measures humidity, not energy content.
- **Option C: Barometer**: This measures atmospheric pressure, which is unrelated to biomass energy content.
- **Option D: Oxanometer**: This is not a standard instrument used for measuring energy content.

4. **Conclusion**: After evaluating the options, the bomb calorimeter is the correct instrument for determining the energy content of biomass. Therefore, the answer is **Option A: Bomb Calorimeter**.
