Experiment to prove that Heat is evolved during Respiration

 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.
