After that place them in one flask and place a thermometer , close it using air tight cork. In another flask place the soaked seed, which is without boiling and place a thermometer and close it using a airtight cork. The thermometer show increase in temperature in the second flask, as its due to germination of seed. In the flask as the life of the seed is already destroyed, so no temperature rise occur.
