Discussion Overview

The discussion revolves around the question of whether adding water to a pot in small increments, allowing each increment to boil before adding the next, would result in boiling 5 gallons of water faster compared to adding the entire volume at once. The scope includes theoretical considerations of heat transfer and practical experimentation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant suggests that adding water in increments may take longer due to heat loss, referencing Newton's law of cooling and the energy required to boil the total volume.
  • Another participant expresses agreement with the idea that heating the entire volume at once could be more efficient, as it minimizes heat loss to the environment.
  • A participant inquires about any experimental comparisons between the two methods, indicating a desire for empirical evidence.
  • One participant mentions plans to conduct a controlled experiment to test the hypothesis but has not yet done so.

Areas of Agreement / Disagreement

Participants express differing views on the efficiency of the two methods, with some supporting the idea that boiling the entire volume at once is preferable, while others are open to testing the concept through experimentation. The discussion remains unresolved as no consensus is reached.

Contextual Notes

The discussion includes assumptions about heat transfer and the efficiency of boiling water, but lacks specific experimental data to support the claims made. The effectiveness of each method may depend on various factors not fully explored in the conversation.

Who May Find This Useful

This discussion may be of interest to individuals exploring thermodynamics, heat transfer, or those considering practical cooking techniques and experiments related to boiling water.

If I have a 1.5 kilowatt range can I get 5 gallons of water boiling faster by introducing it to the pot in small increments and waiting for the water that's already in the pot to start boiling before introducing the next increment or would it be the same amount of time if I just dumped the whole volume in at once? Thanks much in advanced and if I put this in the wrong section I apologize but it seemed like it would be general physics to me.

I don't think so. In fact, I think it could take longer if you don't add the extra water before it starts boiling and if you think about "Newton's law of cooling" (where heat dissipation is proportional to the temperature difference) .

5 gallons of water take a certain amount of joules to boil. If you heat 1 gallon to boil you have added 1/5 of the energy needed. But if it continues to boil, then that extra energy is lost to the environment by water boiling away. Also, your pot is at a hotter temperature relative to the environment so its going to radiate heat away faster. The better thing to do is to heat the whole 5 gallons at once. That way you will lose less heat to the environment via boiling and your water will be spend more time at a temperature closer to ambient and will thus radiate away less heat.

Does that makes sense? I think it does, but its just my first thoughts.

Thank you that is what I thought as well but my friend was arguing otherwise.

Have you tried doing an experiment to compare the two scenarios?
 
Not yet. When get the necessary resources to perform a controlled experiment I plan to.
 
Let us know how you set it up and what the results are!
 
Will do though it may not be for a while.
