Experiment to prove that Heat is evolved during Respiration
Requirements: One Thermo flask, some germinating Gram seeds and athermometer.
Procedure: Some germinating gram seeds are taken in the Thermo flask and closed its mouth tightly with a cork. A thermometer is introduced through the cork so that its bulb rests among the gram seeds. Note themercury reading of the thermometer.
Observation: After some time an increase in theobserved.
Conclusion: Rise of mercury indicates the rise of temperature. And thistemperature is produced by the respiration of the germinating seeds.
