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 andclosed its mouth tightly with a cork. A thermometer is introduced through the cork so that its bulb rests among the gram seeds. Note the mercury reading of the thermometer.
Observation: After some time an increase in the reading of mercury in thethermometer will be observed.
Conclusion: Rise of mercury indicates the rise of temperature. And thistemperature
is produced by the respiration of the germinating seeds.
