Question

Write an activity to show that Respiration produce heat energy​

Answer 1

Answer:

HEY MATE !! HERE IS YOUR ANSWER:

Explanation:

Experiment to demonstrate the energy is production in the form of heat during the respiration:

Requirements:

Thermos bottle (2), cork, thermometer (2), 50 germinating seeds, 50 dry seeds.

Method:

1. Take two thermos bottles fitted with a uni-holed cork.

2. In one thermos fill about 50 germinating seeds and in the other fill about 50 dry seeds.

3. Through the hole of the cork, insert a thermometer in each thermos in a way that its bulb is buried in the seeds (Fig. 47).

Demonstration of production of heat during respiration

4. Note the initial temperature in the thermometer and keep them as such for a few hours. Note the final temperature.

Observations:

There is no change in temperature in the thermometer placed in dry seeds while the temperature rises in the another thermometer which is fitted in the thermos containing germinating seeds.

Results:

: In case of the dry seeds, there is no change in the thermometer reading because they are not undergoing through the process of respiration. But distinct rise in temperature in case of germinating seeds is obviously due to the liberation of heat energy by the respiratory substrate, i.e., germinating seeds.
