https://en.wikipedia.org/wiki/List_of_thermal_conductivities

thermal conductivity changes for materials at different temperatures, and interestingly enough water and salt go in the opposite direction
Sodium chloride
6.5 - 289k
4.85 - 400k

Water
0.5918 - 290k
0.6864 - 400k

stainless steel
16.3 - 24 at 296k depending on composition

so logically speaking, adding salt does speed up the rate the heat should be transferring into the water, as the conductivity should be raising
whether or not this is the same as the salt dissolves into it, as it would not be water, but a solution of water and salt with it's own properties
but if I honestly cared enough about the outcome i'd just try and time it and then probably get called out on timing it wrong somehow, given that this is not a lab and no two pots are identical


but something more important, I was already looking up this information earlier not because of this disagreement, but because I wanted to compare sand and salt

Sand
0.27 303k
Sodium chloride
6.5 - 289k

pretty big difference! sand turns out to be an insulator

I was told somewhere on /ck/ that sand was a good conductor though I knew it was wrong, but it's heat capacity is something im more interested in.
material (cal/gramoC) (J/kgoC)
Salt, NaCl 0.21 880
Sand, quartz 0.19 830

very comparable, so I should be able to substitute the classic and very versatile wok full of sand with a wok full of salt
as sand is heavy and the beach is far.
