Nishigandha kept a vessel containing all the ingredients for making tea in a solar cooker. Shiv ani kept a similar vessel on a stove. Whose tea will be ready first and why?
Answers
Answer:
if nishigandha kept during more sunlight then hers will be ready first but usually the tea on stove will ready first as it provides constant heat
Answer:
Shivani’s tea will be ready and prepared first.
In Shivani’s case, the intensity of the flame that is in contact with the vessel is extremely high due to which the flow of heat into the vessel containing water will be faster. Thus, the time taken for the water to boil will be less. Hence, preparing tea in this case will be faster and convenient.
In the case of Nishigandha, the intensity of radiation that reaches the vessel is not as high in comparison to the stove’s flame. Thus, the flow of heat will be lower and slower in this case and the time taken to reach the boiling temperature of the tea will be more. Hence, tea prepared through this method would be at a slower rate.
